Revision history for Perl extension Coro.

TODO: possibly convert some of the Event modules into AnyEvent users.

TODO: eg/lwp to use Coro::Select
        - should compile with perl 5.9.x now.
        - reuse PL_start_env for all coros, saves some memory per coroutine.
        - manage PL_top_env differently, hopefully to avoid panic: top_env.
        - timeout argument was not properly used in Coro::Socket.
        - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
        - made Coro::Util an AnyEvent user, moved it to Coro/.
        - remove "FATAL: uncaught exception" prefix. coroutines that die
          kill the whole process, just as exceptions in the main coroutine
          do.

2.1  Wed Nov  1 23:01:13 CET 2006
        - fix a long-standing bug in Coro::Select where select with
          zero timeout would instead change the current default filehandle.
        - use a simpler and hopefully more robust way to clone padlists
          (uses less memory and a perl function instead of our own).
        - coro can now create a stack guard area on many architectures.
        - Coro::AIO properly reexports additional functions from IO::AIO.
        - updated libcoro with a workaround for OS X,
          pach and testing by Michael Schwern.

2.0  Tue Oct 24 05:47:17 CEST 2006
        - support additional aio requests in Coro::AIO.

1.9  (never properly released due to a glitch)

1.8  Thu Feb  2 00:59:06 CET 2006
        - applied suggested patch by SAMV to avoid problems during stupid
          mark & sweep gc run.
        - applied patch by Scott Walters for 5.9.3 compatibility.

1.7  Tue Dec 27 01:41:58 CET 2005
        - added Coro::AIO, a thin wrapper around IO::AIO.
        - improved Makefile.PL explanations.

1.6  Mon Dec 12 21:30:05 CET 2005
        - additionally save PM_curpm might fix as-of-yet
          unseen problems with regex matches being attributed to the
          wrong package.
        - add t/10_bugs.t, which currently checks against imho broken
          perls that use 0.26MB of stack space per Perl_magic_get
          invocation (newer linuxes) as opposed to the 0.0002MB perl
          normally uses.
        - make stacksize configurable for the ultimate debian experience.

1.51 Mon Dec 12 18:48:36 CET 2005
        - remove debugging warn() accidentally left in Coro::Select.

1.5  Tue Nov 29 13:32:44 CET 2005
        - use Coro::Event inside Coro::Select to avoid spurious deadlocks.
        - fix Coro::Select 'select'.
        - strict'ify some modules.
        - libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
        - use XSLoader in selected modules.
        - remove some 5.6 compatibility cruft.

1.4  Tue Sep  6 00:11:05 CEST 2005
        - libcoro did not take into account the trampoline on amd64,
          when 'l'inux method was used.

1.31 Tue Aug 30 23:31:33 CEST 2005
        - some portability fixes/workarounds.

1.3  Sat Aug 20 03:08:56 CEST 2005
        - no code changes. module seems to work fine.
        - improve Coro::State docs, remove reference to nonexisting
          Coro::State::flush method.
        - no longer autodetect windows, present it as an option instead.

1.2  Mon May 16 02:00:55 CEST 2005
        - included libcoro.c earlier in State.xs, might improve portability.
        - use a faster and possibly more stable Coro::Cont implementation.
        - accept x86_64 in addition to amd64 for optimized linux-amd64 support.
        - fix bugs Coro::SemaphoreSet that could cause locks never to be freed.
        - fix bugs in CoroAPI.h and document it in Coro::MakeMaker.

1.11 Thu Mar  3 18:00:52 CET 2005
        - change of contact address.

1.1 Tue Feb 22 20:51:16 CET 2005
        - support [l]inux method on amd64.
        - allow some context switches while compiling/eval'ing.

1.0  Tue Aug 10 03:47:27 CEST 2004
        - Event 0.89 fixes the bug again.
        - fix the remaining(??) memleak. I didn't free the cache-AV for
          padlists, so one AV per created anon-sub leaked.

0.97 Fri May 14 15:23:32 CEST 2004
        - remove stupid gcc extension that was an experiment only anyway.

0.96 Thu May 13 18:09:29 CEST 2004
        - tell people if they have yet another broken Event variant.
        - made Coro to work _better_ with threads (it seems that, as long
          as you use Coros in one thread only everything will work fine.
          Looking at the perl source the problem might be missing locking
          between Coro and some perl internal routines. That's not easily
          fixable).
        - (hopefully) got rid of the static xnext inside transfer.

0.95 Sun Feb 15 03:20:28 CET 2004
        - removed Coro::State::flush, implemented a new and much
          faster caching mechanism by attaching magic to the CV.
        - a memleak with (real) closures remains.
        - dramatically reduced size of stacks to 65536 (linux/x86), after
          observing that even myhttpd never had more than a kilobyte
          of stack in use (stack is still only physically allocated in
          pagesize increments for systems suporting mmap).
        - fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
        - fix for threaded perl.

0.9  Sun Nov 23 04:32:39 CET 2003
        - fix a few very hard to track down but (of course) stupid
          memory leaks.
        - stringify version number to avoid locale problems :(.
        - perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
          hopefully ignoring it "just works".

0.8   Wed Nov  5 19:38:40 CET 2003
        - port to perl5.005_03, but only 5.8.x+ is supported!
        - honor LocalAddr even without LocalPort in Coro::Socket.

0.7   Tue May 27 03:12:38 CEST 2003
        - the version jump indicates some level of testing, not gobs
          of new features.
        - uh... I found the prompt function in ExtUtils::MakeMaker.
          Highly correct stuff, that is...
        - fixed(?) a bug with die's in coroutines causing "panic: top_env".
          the fix is not well understood by the author, so beware :(.

0.652 Thu May  8 02:54:46 CEST 2003
        - Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
          cause version 4 doesn't have ucontext.
        - Benjamin Reed reported that setjmp works fine on darwin,
          so preselect it.

0.651 Sat Mar 29 15:00:23 CET 2003
        - fix a bug in Coro::Handle where some bytes could get lost
          on reading, reported by jason@nichego.net.

0.65  Sun Mar 23 00:08:26 CET 2003
        - added a README.linux-glibc.
        - new module Coro::Select.
        - also save/restore PL_comppad, fixes segfaults with 5.8.1.
          (I never claimed that I know what I am doing ;).
        - set default to setjmp/longjmp on non-x86-linux.

0.6   Thu Nov 21 11:09:06 CET 2002
        - made lazy context switching the default.
        - fixed the bug where SemaphoreSet::guard
          was the same as timed_guard and timed_guard was missing.
        - fix a memleak in Coro::Timer.
        - reclassified context sharing as not experimental.

0.534 Sun Apr 14 03:05:12 CEST 2002
        - fixed backspace => tab in header parsing (myhttpd).
        - added eg/readline, for elmex.
        - Coro::Event now calls ->start on first call instead of
          ->again, which created wrong timeouts for the first ->next.
        - fixed a bug where Coro::Socket returned a closed socket instead
          of nothing on ECONNREFUSED and similar error conditions.

0.533 Mon Feb 18 18:49:40 CET 2002
        - adapt to finally working Event-0.85.
        - fixed buggy event initialization (trapped under windows, but how
          could it possibly have worked anywhere?)

0.532 Wed Jan 16 02:45:32 CET 2002
        - removed the reference to pp_entersub, might work on
          (some) win32 perls now (testsuite works under cygwin,
          without Event, which freezes).

0.531 Mon Dec 10 22:18:44 CET 2001
        - Fixed a bug in SemaphoreSet::timed_down.

0.53  Tue Nov 27 21:11:13 CET 2001
        - some tests for Event.
        - slightly different internal architecture to get refcnt into the object
          and not the reference. might fix a few bugs, certainly did introduce
          new ones.
        - Coro::Timer (independent of Event).
        - new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.

0.52  Tue Nov  6 21:36:18 CET 2001
        - ported to cygwin (trivial).
          patch by Gerrit P. Haase <gp@familiehaase.de>.
        - small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.

0.51  Thu Nov  1 20:39:01 CET 2001
        - terminate/cancel now work properly (otherwise termination
          could cause a "next coroutine is not and contains not..."
          error.
        - added Coro::Socket::shutdown.
        - Coro::Event::loop no is the same as Event::loop.
        - implemented terminate with args + join.

0.5   Fri Sep 28 16:15:35 CEST 2001
        - fixed "print" on a Coro::Handle. The print method worked.
        - small tweaks (seem to reduce memory consumption a lot)
          in various modules.
        - splendid use of "no warnings" scattered throughout.
        - added Coro::Handle::rbuf, fixed Coro::Handle::fh.

0.49  Sun Sep 16 02:42:45 CEST 2001
        - changed some method calls to function calls for speed
          inside Coro::Handle.
        - make Coro::Handle use an array instead of a hash for
          speed reasons.
        - IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
          sjlj and ucontext should now work.
        - IRIX-specific port for libcoro.
        - swapped order of accept results to match IO::Socket.
        - changed getsock/peername to sock/peername to match IO::Socket.
        - fixed a bug that caused segfault when returning to main task
          under some circumstances.
        - other bugfixes.

0.45  Sun Sep  2 02:54:01 CEST 2001
        - new method Coro::Handle::timeout.
        - corrected speling of set...name to get...name in Coro::Socket.
        - Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
        - Coro::Handle now supports fileno and FILENO.
        - added eg/myhttpd, a web server.
        - Coro::Socket now accepts numeric ports as well as "port(number)"
          syntax.
        - moved some scheduling primitives into xs code. more to come.
        - new simple priority system.
        - implemented Coro::Event using XS, almost four times faster!
        - small memory corruption problem fixed (boy that was difficult).

0.13  Wed Aug  8 16:53:07 CEST 2001
        - new method Coro::Handle::readline.
        - added eg/lwp and Coro::Handle::autoflush, to make LWP work.
          (see eg/lwp on how to make LWP non-blocking).
        - renamed Coro::Socket::new_inet to new.
        - added Coro::Util, some utility functions.
        - die/eval now works better (still get annoying (but true ;)
          "Callback called exit" messages).
        - Coro::Handle now supports timeout, and Coro::Socket Timeout.
        - much better Coro::Socket support.

0.12  Fri Jul 27 04:19:01 CEST 2001
        - do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
        - very experimental stack sharing algorithm. not 100% safe but
          should work well in practise ;)
        - added Coro::RWLock.
        - Coro::Specific now works.

0.11  Tue Jul 24 22:49:21 CEST 2001
        - added specialized hack for newer and older linux versions (fast).
        - renamed Coro::Event::IO to Coro::Handle.
        - new module Coro::Socket.

0.1   Tue Jul 24 01:47:53 CEST 2001
        - release candidate 3. A rather new internal structure :(
        - the great renaming: Damian Conway gave me a suitable replacement
          for yield.
        - added Coro/libcoro, a portable coroutine implementation for C
          (not even perl-dependent!!!), which can be used by Coro::State.
        - renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
          perl-5.6.
        - new function Coro::Event::idle.
        - the idle process is now overriden
          by default in Coro::Event.
        - Coro::Channel now enforces the size.
        - canceling events now works in all cases.
        - Coro state now include $_ and $@.
        - yet another bug workaround that I do not really understand :(
        - new module Coro::Event::IO (very undocumented) to do
          non-blocking i/o.
        - performance tuning.

0.08  Thu Jul 19 06:13:25 CEST 2001
        - release candidate 2 (new functionality).
        - add Coro::State::flush function.
        - transfer now supports a flags value (mostly for speed ATM).
        - might compile and work in the presence of threads now.
        - continuations have a saner syntax.
        - no more memleaks.

0.07  Tue Jul 17 17:40:18 CEST 2001
        - release candidate 1 ;)
        - slightly nicer code.
        - fixed a scheduling bug in Coro::Event.

0.06  Tue Jul 17 04:23:24 CEST 2001
        - ok, I found the showstopper - the same sub must not be
          re-entered in two different coroutines, otherwise => crash. I
          see no easy solution to this problem, except by walking the call
          chaing and saving/restoring the cv's, which is what I do now.
        - memory leaks still latent, especially at thread termination.
        - Coro::Event now works (haha).

0.05  Sun Jul 15 17:32:20 CEST 2001
        - fixed a few issues in Coro::Event.
        - I forgot to include Coro::Event in 0.04 :(:(:(

0.04  Sun Jul 15 05:24:59 CEST 2001
        - @_ is now properly localized.
        - Coro::State is now easier subclassable.
        - Coro::Cont now coroutine-aware.
        - Coro::Specific is a low-overhead module to create
          coroutine-specific vars.
        - Coro::Event provides a simple interface to Event.

0.03  Fri Jul 13 14:51:52 CEST 2001
        - transfer() now implemented in XS (beware).
        - new module Coro::Cont for really faked continuations.
        - big internal architecture changes: Coro::State is now
          really low-level and can thus be used to implement other
          interesting things, While "Coro::" implements a process-like
          model. Still crude and subject to change.
        - $_ and $@ are no longer being localized.

0.02  Tue Jul 10 01:38:17 CEST 2001
        - implemented "async" attribute.
        - $_ and $@ are now localized.
        - added Coro::Channel.
        - more testcases, still no docs.

0.01  Tue Jul  3 02:18:41 CEST 2001
        - original version; copied from Convert::Scalar.

87	root	1.97
88	root	1.96	1.0 Tue Aug 10 03:47:27 CEST 2004
89	root	1.95	- Event 0.89 fixes the bug again.
90	root	1.96	- fix the remaining(??) memleak. I didn't free the cache-AV for
91			padlists, so one AV per created anon-sub leaked.
92	root	1.95
93	pcg	1.94	0.97 Fri May 14 15:23:32 CEST 2004
94			- remove stupid gcc extension that was an experiment only anyway.
95
96	pcg	1.93	0.96 Thu May 13 18:09:29 CEST 2004
97	root	1.103	- tell people if they have yet another broken Event variant.
98	pcg	1.91	- made Coro to work _better_ with threads (it seems that, as long
99			as you use Coros in one thread only everything will work fine.
100			Looking at the perl source the problem might be missing locking
101			between Coro and some perl internal routines. That's not easily
102			fixable).
103	pcg	1.92	- (hopefully) got rid of the static xnext inside transfer.
104	pcg	1.91
105	pcg	1.90	0.95 Sun Feb 15 03:20:28 CET 2004
106	pcg	1.86	- removed Coro::State::flush, implemented a new and much
107			faster caching mechanism by attaching magic to the CV.
108	pcg	1.87	- a memleak with (real) closures remains.
109	pcg	1.88	- dramatically reduced size of stacks to 65536 (linux/x86), after
110			observing that even myhttpd never had more than a kilobyte
111			of stack in use (stack is still only physically allocated in
112			pagesize increments for systems suporting mmap).
113	pcg	1.89	- fix for a "cygwin-64" architecture added, proposed by Stefan Traby.
114	pcg	1.90	- fix for threaded perl.
115	pcg	1.86
116	pcg	1.85	0.9 Sun Nov 23 04:32:39 CET 2003
117	pcg	1.84	- fix a few very hard to track down but (of course) stupid
118			memory leaks.
119			- stringify version number to avoid locale problems :(.
120	pcg	1.85	- perl 5.9.0 does not have SvPADBUSY, reported by Scott Walters,
121			hopefully ignoring it "just works".
122	pcg	1.84
123	pcg	1.83	0.8 Wed Nov 5 19:38:40 CET 2003
124			- port to perl5.005_03, but only 5.8.x+ is supported!
125	pcg	1.82	- honor LocalAddr even without LocalPort in Coro::Socket.
126
127	root	1.81	0.7 Tue May 27 03:12:38 CEST 2003
128			- the version jump indicates some level of testing, not gobs
129			of new features.
130	root	1.80	- uh... I found the prompt function in ExtUtils::MakeMaker.
131			Highly correct stuff, that is...
132	root	1.81	- fixed(?) a bug with die's in coroutines causing "panic: top_env".
133			the fix is not well understood by the author, so beware :(.
134	root	1.80
135	root	1.79	0.652 Thu May 8 02:54:46 CEST 2003
136	root	1.76	- Applied patch by Slaven Rezic to set default to "s" on FreeBSD,
137	root	1.78	cause version 4 doesn't have ucontext.
138	root	1.77	- Benjamin Reed reported that setjmp works fine on darwin,
139			so preselect it.
140	root	1.76
141	root	1.75	0.651 Sat Mar 29 15:00:23 CET 2003
142			- fix a bug in Coro::Handle where some bytes could get lost
143			on reading, reported by jason@nichego.net.
144	root	1.74
145	root	1.73	0.65 Sun Mar 23 00:08:26 CET 2003
146	root	1.72	- added a README.linux-glibc.
147			- new module Coro::Select.
148			- also save/restore PL_comppad, fixes segfaults with 5.8.1.
149			(I never claimed that I know what I am doing ;).
150	root	1.73	- set default to setjmp/longjmp on non-x86-linux.
151	root	1.72
152	root	1.71	0.6 Thu Nov 21 11:09:06 CET 2002
153			- made lazy context switching the default.
154			- fixed the bug where SemaphoreSet::guard
155			was the same as timed_guard and timed_guard was missing.
156			- fix a memleak in Coro::Timer.
157			- reclassified context sharing as not experimental.
158
159	root	1.70	0.534 Sun Apr 14 03:05:12 CEST 2002
160	root	1.69	- fixed backspace => tab in header parsing (myhttpd).
161	root	1.70	- added eg/readline, for elmex.
162			- Coro::Event now calls ->start on first call instead of
163			->again, which created wrong timeouts for the first ->next.
164			- fixed a bug where Coro::Socket returned a closed socket instead
165			of nothing on ECONNREFUSED and similar error conditions.
166	root	1.69
167	root	1.68	0.533 Mon Feb 18 18:49:40 CET 2002
168			- adapt to finally working Event-0.85.
169			- fixed buggy event initialization (trapped under windows, but how
170			could it possibly have worked anywhere?)
171
172	root	1.67	0.532 Wed Jan 16 02:45:32 CET 2002
173	root	1.66	- removed the reference to pp_entersub, might work on
174			(some) win32 perls now (testsuite works under cygwin,
175			without Event, which freezes).
176	root	1.65
177	root	1.64	0.531 Mon Dec 10 22:18:44 CET 2001
178	root	1.63	- Fixed a bug in SemaphoreSet::timed_down.
179
180	root	1.64	0.53 Tue Nov 27 21:11:13 CET 2001
181	root	1.60	- some tests for Event.
182	root	1.61	- slightly different internal architecture to get refcnt into the object
183			and not the reference. might fix a few bugs, certainly did introduce
184			new ones.
185			- Coro::Timer (independent of Event).
186	root	1.62	- new timed_wait functions for Coro::Signal, Semaphore, SemaphoreSet.
187	root	1.60
188	root	1.64	0.52 Tue Nov 6 21:36:18 CET 2001
189	root	1.58	- ported to cygwin (trivial).
190			patch by Gerrit P. Haase <gp@familiehaase.de>.
191			- small setjmp code fix by Sullivan.DanielJ@epamail.epa.gov.
192
193	root	1.64	0.51 Thu Nov 1 20:39:01 CET 2001
194	root	1.54	- terminate/cancel now work properly (otherwise termination
195			could cause a "next coroutine is not and contains not..."
196			error.
197	root	1.55	- added Coro::Socket::shutdown.
198	root	1.56	- Coro::Event::loop no is the same as Event::loop.
199			- implemented terminate with args + join.
200	root	1.54
201	root	1.64	0.5 Fri Sep 28 16:15:35 CEST 2001
202	root	1.53	- fixed "print" on a Coro::Handle. The print method worked.
203	root	1.50	- small tweaks (seem to reduce memory consumption a lot)
204			in various modules.
205			- splendid use of "no warnings" scattered throughout.
206	root	1.52	- added Coro::Handle::rbuf, fixed Coro::Handle::fh.
207	root	1.48
208	root	1.47	0.49 Sun Sep 16 02:42:45 CEST 2001
209	root	1.43	- changed some method calls to function calls for speed
210			inside Coro::Handle.
211	root	1.44	- make Coro::Handle use an array instead of a hash for
212			speed reasons.
213			- IRIX mystery solved: it's SGI's NT, after all: "standard, huh?".
214			sjlj and ucontext should now work.
215			- IRIX-specific port for libcoro.
216	root	1.45	- swapped order of accept results to match IO::Socket.
217	root	1.46	- changed getsock/peername to sock/peername to match IO::Socket.
218			- fixed a bug that caused segfault when returning to main task
219			under some circumstances.
220			- other bugfixes.
221	root	1.43
222	root	1.42	0.45 Sun Sep 2 02:54:01 CEST 2001
223	root	1.36	- new method Coro::Handle::timeout.
224			- corrected speling of set...name to get...name in Coro::Socket.
225			- Coro::Socket::accept now returns a Coro::Socket, not a Coro::Handle.
226			- Coro::Handle now supports fileno and FILENO.
227			- added eg/myhttpd, a web server.
228	root	1.37	- Coro::Socket now accepts numeric ports as well as "port(number)"
229			syntax.
230	root	1.38	- moved some scheduling primitives into xs code. more to come.
231	root	1.39	- new simple priority system.
232	root	1.40	- implemented Coro::Event using XS, almost four times faster!
233	root	1.41	- small memory corruption problem fixed (boy that was difficult).
234	root	1.36
235	root	1.35	0.13 Wed Aug 8 16:53:07 CEST 2001
236	root	1.31	- new method Coro::Handle::readline.
237	root	1.34	- added eg/lwp and Coro::Handle::autoflush, to make LWP work.
238			(see eg/lwp on how to make LWP non-blocking).
239	root	1.31	- renamed Coro::Socket::new_inet to new.
240	root	1.32	- added Coro::Util, some utility functions.
241	root	1.33	- die/eval now works better (still get annoying (but true ;)
242			"Callback called exit" messages).
243	root	1.34	- Coro::Handle now supports timeout, and Coro::Socket Timeout.
244			- much better Coro::Socket support.
245	root	1.31
246			0.12 Fri Jul 27 04:19:01 CEST 2001
247	root	1.29	- do not use mmap if neither MAP_ANON nor MAP_ANONYMOUS is defined.
248	root	1.34	- very experimental stack sharing algorithm. not 100% safe but
249	root	1.28	should work well in practise ;)
250	root	1.30	- added Coro::RWLock.
251	root	1.31	- Coro::Specific now works.
252	root	1.28
253			0.11 Tue Jul 24 22:49:21 CEST 2001
254	root	1.27	- added specialized hack for newer and older linux versions (fast).
255			- renamed Coro::Event::IO to Coro::Handle.
256			- new module Coro::Socket.
257
258	root	1.26	0.1 Tue Jul 24 01:47:53 CEST 2001
259	root	1.23	- release candidate 3. A rather new internal structure :(
260	root	1.24	- the great renaming: Damian Conway gave me a suitable replacement
261			for yield.
262	root	1.23	- added Coro/libcoro, a portable coroutine implementation for C
263	root	1.22	(not even perl-dependent!!!), which can be used by Coro::State.
264	root	1.20	- renamed SAVE_DEFSV (on xs-level only) to avoid symbol clash in
265			perl-5.6.
266	root	1.16	- new function Coro::Event::idle.
267			- the idle process is now overriden
268			by default in Coro::Event.
269	root	1.17	- Coro::Channel now enforces the size.
270	root	1.18	- canceling events now works in all cases.
271	root	1.19	- Coro state now include $_ and $@.
272			- yet another bug workaround that I do not really understand :(
273	root	1.21	- new module Coro::Event::IO (very undocumented) to do
274			non-blocking i/o.
275	root	1.25	- performance tuning.
276	root	1.16
277	root	1.15	0.08 Thu Jul 19 06:13:25 CEST 2001
278	root	1.14	- release candidate 2 (new functionality).
279	root	1.13	- add Coro::State::flush function.
280			- transfer now supports a flags value (mostly for speed ATM).
281			- might compile and work in the presence of threads now.
282	root	1.14	- continuations have a saner syntax.
283	root	1.19	- no more memleaks.
284	root	1.13
285	root	1.12	0.07 Tue Jul 17 17:40:18 CEST 2001
286			- release candidate 1 ;)
287			- slightly nicer code.
288			- fixed a scheduling bug in Coro::Event.
289
290	root	1.11	0.06 Tue Jul 17 04:23:24 CEST 2001
291			- ok, I found the showstopper - the same sub must not be
292	root	1.9	re-entered in two different coroutines, otherwise => crash. I
293			see no easy solution to this problem, except by walking the call
294			chaing and saving/restoring the cv's, which is what I do now.
295	root	1.11	- memory leaks still latent, especially at thread termination.
296			- Coro::Event now works (haha).
297	root	1.9
298	root	1.8	0.05 Sun Jul 15 17:32:20 CEST 2001
299			- fixed a few issues in Coro::Event.
300			- I forgot to include Coro::Event in 0.04 :(:(:(
301
302	root	1.7	0.04 Sun Jul 15 05:24:59 CEST 2001
303	root	1.5	- @_ is now properly localized.
304	root	1.4	- Coro::State is now easier subclassable.
305			- Coro::Cont now coroutine-aware.
306			- Coro::Specific is a low-overhead module to create
307			coroutine-specific vars.
308	root	1.6	- Coro::Event provides a simple interface to Event.
309	root	1.4
310	root	1.3	0.03 Fri Jul 13 14:51:52 CEST 2001
311	root	1.4	- transfer() now implemented in XS (beware).
312			- new module Coro::Cont for really faked continuations.
313			- big internal architecture changes: Coro::State is now
314	root	1.3	really low-level and can thus be used to implement other
315	root	1.4	interesting things, While "Coro::" implements a process-like
316			model. Still crude and subject to change.
317	root	1.3	- $_ and $@ are no longer being localized.
318
319	root	1.2	0.02 Tue Jul 10 01:38:17 CEST 2001
320			- implemented "async" attribute.
321			- $_ and $@ are now localized.
322			- added Coro::Channel.
323			- more testcases, still no docs.
324
325	root	1.1	0.01 Tue Jul 3 02:18:41 CEST 2001
326			- original version; copied from Convert::Scalar.
327
