2 2
3TODO: should explore PerlIO::coroaio (perl leaks like hell). 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: maybe implement a default message channel, very much like Erlang's 4TODO: channel->maxsize(newsize)?
5 actor model (which is cool in a lot of important aspects (failures!), 5TODO: __GCC_HAVE_DWARF2_CFI_ASM
6 but very lacking in others (higher level ipc)). 6TODO: swap_sv, maybe add scope_swap_sv, andallow to unswap by repeat?
7TODO: swap_sv not undone in pool
8TODO: croak when async_pool triesd to run canceled thread?

8TODO: testcancel 106.42 Wed Feb 11 20:29:52 CET 2015
9TODO: aio 11 - Coro::SemaphoreSet->try did not actually work (analyzed by
10TODO: Coro::Semaphore 12 SATO Kentaro).
115.0 13 - upgrade libecb to be C11 compliant.
12 - NEW ARCHITECTURE: use 4.912 for the stable version. 14
156.41 Sat Sep 6 22:08:46 CEST 2014
16 - restore portability to perl 5.8.x.
17 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
18 up some memory, but fixes "use feature" and similar modules
19 when used inside a Coro.
20 - allow zero as argument to Coro::Channel to mean the same thing
21 as no argument. this works with older versions as well,
22 but wasn't legal until now.
23 - slightly better c header file detection.
24
256.39 Mon Jun 2 00:00:08 CEST 2014
26 - work around more incompatible changes in 5.20.
27
286.38 Sun Jun 1 21:54:23 CEST 2014
29 - check that perl slots actually have enough space to hold
30 interpreter variables.
31 - untested port to perl 5.19 (64 bit tmps indices) (reported
32 by Andreas König).
33 - croak when cancel is called without a thread context.
34
356.37 Tue Mar 4 13:27:33 CET 2014
36 - *sigh*, removed leftover debugging code from debugging a
37 perl bug, of all things.
38
396.36 Tue Mar 4 07:11:59 CET 2014
40 - semaphores would not clear the destroy hook when interrupted
41 by ->throw, causing segfaults or worse.
42 - ->throw on a thread waiting for a semaphore did not acquire
43 the semaphore, but also didn't wake up other waiters,
44 possibly causing a deadlock.
45 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
46 to report a full stacktrace, which should help find out
47 where the actual call is.
48 - "atomically" destroy data in slf_destroy, because it is
49 the right thing to do, just in case.
50 - disable ecb.h libm dependency, to compile on ancient systems
51 or under adverse conditions.
52
536.33 Mon Nov 18 11:26:27 CET 2013
54 - do not crash when freeing padlists with holes (in 5.18).
55 - tentative SVt_BIND 5.19 port/fix.
56
576.32 Tue Nov 5 15:35:35 CET 2013
58 - use a new algorithm to derive padlists for perl 5.18. The old
59 one could lead to 0-pointer accesses inside perl (reported
60 by Darin McBride).
61
626.31 Thu May 9 07:39:48 CEST 2013
63 - Coro::AIO requests would crash if the thread was ready'd
64 while the request was ongoing.
65
666.29 Wed May 8 02:55:18 CEST 2013
67 - when an on_destroy handler destructs the coro currently being
68 destructed a perl scalar could be accessed after being freed,
69 likely causing a crash.
70
716.28 Wed Mar 6 06:58:02 CET 2013
72 - clean remnants of existing __DIE__ and __WARN__ handlers so
73 they lose their magic and will not cause segfaults later
74 (testcase by Andrey Sagulin).
75 - improved Coro::State documentation a bit.
76 - Coro::Debug::command now flushes the output.
77 - add hack detection code for x32 abi, because the braindead slugs
78 who designed that made it look exactly like x86_64 without
79 providing proper compile time symbols to test for it. as a result,
80 this detection cannot work reliably.
81 - valgrind stack registering was broken.
82 - do not rely on Time::HiRes anymore in Coro::Debug.
83
846.23 Fri Dec 7 23:36:37 CET 2012
85 - use experimental fiber implementation on native windows
86 perls.
87 - use sizeof (void *) as multiplication factor for stack sizes,
88 to accomodate the totally braindamaged microsoft 64 bit "os".
89 - changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
90 activeperl 5.16 crashes when PerlIO_define_layer is called due
91 to some bug in the perl dll, strawberry perl at least passes
92 the testsuite.
93 - implement Coro::Handle->peeraddr/host/port, for slightly
94 improved compatibility with LWP.
95 - implement 5.17 compatibility by almost blindly applying a
96 good-looking patch by Father Chrysostomos.
97 - move stack management functions into libcoro 3.
98 - libcoro version 3 "released".
99 - support magic values as timed_io_once args.
100 - recommend AnyEvent 7+ or EV 4+, also require EV
101 version 4 or newer for Coro::EV.
102
1036.10 Tue Oct 9 01:14:27 CEST 2012
104 - updated ecb.h, it had a typo that caused it to not compile on many
105 big endian systems (reported by many people).
106 - disable memory fences in ecb.h to improve portability.
107
1086.09 Sat Oct 6 23:25:02 CEST 2012
109 - Coro::EV I/O watchers were not interruptible by exceptions
110 (Coro::State::throw) (testcase by sten).
111 - ->throw now puts threads into the ready queue, as this seems to
112 be expected by existing code, and code that doesn't cope with spurious
113 wakeups needs fixing anyway.
114 - use fd -1 in mmap.
115 - cast I32 to int in error message printf.
116 - warn about broken so-called "hardened" kernels.
117
1186.08 Fri Apr 13 12:05:47 CEST 2012
119 - be more aggressive about exiting like perl does - formerly,
120 exiting from the non-main thread would not execute END blocks.
121
1226.07 Fri Nov 11 21:21:48 CET 2011
123 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
124 - update ecb.h.
125
1266.06 Mon Aug 8 23:59:48 CEST 2011
127 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
128 backend, which is an order of magnitude slower. unfortunately, cygwins
129 pthread implementation isn't very complete either, so allocate the stack
130 twice just to be sure.
131 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
132 in its ithreaded perl - best recompile cygwin and use the 'w'indows
133 backend for much better performance. also disable ithreads for
134 even better performance...).
135
1366.05 Thu Aug 4 21:36:36 CEST 2011
137 - blush, condvar values would not be propagated from send to recv anymore
138 (reported by Chip Salzenberg).
139 - use exponential increase for the readline buffer length in
140 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
141
1426.04 Wed Aug 3 17:15:45 CEST 2011
143 - use even more efficient and more compatible condvars for
144 compatibility to AnyEvent 6.x :)
145 - more inconsequential ecb.h updates.
146
1476.03 Wed Aug 3 11:41:30 CEST 2011
148 - change how Coro patches AnyEvent condvars for compatibility to
149 AnyEvent 6.x.
150 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
151 hasn't been included.
152
1536.02 Wed Jul 13 04:35:19 CEST 2011
154 - "improve portability to Gentoo" - gentoo manages to put perl variables
155 in memory areas that are farther than 2gb apart, which the jit couldn't
156 handle and barfed. now it's just a bit slower on gentoo and similar
157 systems.
158
1596.01 Sun Jul 3 12:31:14 CEST 2011
160 - workarounds are good, but the test for whether pthreads are used
161 was not good. this one should be better.
162 - check differently whether gcc generates cfi instructions itself.
163
1646.0 Wed Jun 29 19:43:35 CEST 2011
165 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
166 destroyed and cleaned up automatically (e.g. async { schedule }).
167 - implement a JIT compiler for part of the thread switch code,
168 which gives a 50% speed improvement on threaded perls, and
169 about 4% on non-threaded perls (so threaded perls now finally
170 reach about half the speed of non-threaded perls).
171 - slightly modernise Coro::Intro, add section about rouse functions.
172 - avoid DEFSV and ERRSV, giving another 10% improvement
173 in thread switching.
174 - Coro::State->is_destroyed is now called is_zombie.
175 - implement a Coro->safe_cancel method that might fail, but
176 cancels in a "safer" way if it succeeds.
177 - add preliminary support for DEBUGGING perls.
178 - get rid of two hash-accesses when initialising a new Coro - this
179 speeds up coro creation by almost a factor of two.
180 - croak when a coro that is being cancelled tries to block
181 (e.g. while executing a guard block), instead of crashing or
182 deadlocking.
183 - use a more robust and also faster method to identify Coro::State
184 objects - speeds up everything a bit.
185 - implement Coro->cancel in XS for a 20% speed improvement, and to
186 be able to implement mutual cancellation.
187 - speed up context switches by a percent or two by more efficiently
188 allocating context stack entries.
189 - implement Coro->join and Coro->on_destroy in XS for a speedup and
190 a reduction in memory use.
191 - cancelling a coro while it itself is cancelling another coro is
192 now supported and working, instead of triggering an assertion.
193 - be a bit more crash-resistant when calling (buggy) on_destroy
194 callbacks (best effort).
195 - move on_destroy into the slf_frame, to allow extension slf
196 functions to have destructors.
197 - get rid if coro refcounting - simply crash in other interpreter
198 threads by nulling the pointers on clone.
199 - simplify warn/die hook handling when loading Coro - the convoluted
200 logic seems to be no longer neccessary.
201 - use libecb instead of our own home-grown gcc hacks.
202 - document alternatives to Coro::LWP. Please use them :)
203 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
204 sigaltstack. Really. wine suffers from it, erlang suffers from it,
205 and it's known since at least 2006.
206
2075.372 Wed Feb 23 06:14:30 CET 2011
208 - apparently mingw doesn't provide a working gettimeofday, try to
209 work around that by relying on Time::HiRes (indirectly brought to
210 my attention by Max Maischein).
211 - fix some portability issues when Time::HiRes was used.
212
2135.371 Mon Feb 21 14:36:08 CET 2011
214 - backport to windows process emulation code again.
215
2165.37 Sat Feb 19 07:49:44 CET 2011
217 - add a big "Coro thread life cycle" section to "man Coro".
218 - try a tentative workaround against the breakage that 5.13 has
219 introduced without depreciation period. sigh.
220 - no longer use Time::HiRes if gettimeofday is available, which
221 saves quite a lot of memory.
222
2235.36 Sun Feb 13 05:33:41 CET 2011
224 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
225 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
226 method call.
227 - undocument Coro::Timer::sleep and obsolete whole module.
228 - optimise Coro::Timer::timeout memory and cpu usage.
229 - slightly updated Coro::Intro for recent changes.
230 - do not initialise PL_dirty anymore.
231
2325.25 Thu Nov 11 01:08:39 CET 2010
233 - try a different approach on netbsd - netbsd 5 finally has marginally
234 working pthreads, but still broken ucontext/sigaltstack.
235 - openbsd 4.8 finally got their act together, Coro works out of the box
236 with asm, setjmp and pthreads (no change, just informational).
237
2385.24 Sat Oct 23 11:27:12 CEST 2010
239 - port to the EV 4.0 API.
240 - work around bugs in mingw32, making strawberry perl work
241 out of the box.
242 - correctly modify Coro::AIO function prototypes
243 so that they reflect the "no optional parameters" rule.
244 - "ported" libcoro to C++.
245
2465.23 Mon May 17 18:50:42 CEST 2010
247 - be more resistant to ordering changes when initialising
248 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
249 Waldorf).
250 - document that perl 5.12 deliberately removed support for cloning.
251
2525.22 Wed Apr 14 03:55:35 CEST 2010
253 - correctly return udnef on errors in Coro::Handle::read/write
254 (testcase by Marc Mims).
255 - convert Coro::Util into a "perl compatibility wrapper" - the functions
256 are less useful now, but are drop-in replacements for existing
257 functions, listing better alternatives in the documentation. This also
258 fixes a bug in Coro::LWP which naively substituted Socket::inet_aton
259 with Coro::Util::inet_aton.
260 - do not override $Coro::idle unconditionally in Coro.pm, as other
261 modules could have provided their own idle coro already
262 (for exmaple, Coro::AnyEvent).
263 - fix Coro::Util::gethost* functions.
264 - Coro::Timer corretcly exports it's symbols (reported by Hideki Yamamura).
265
2665.21 Wed Dec 16 07:19:51 CET 2009
267 - automatically load Coro::AnyEvent when AnyEvent and Coro are used
268 together.
269 - add some examples on how to combine other event loops with Coro in
270 Coro::AnyEvent, and how to run it (and not to block). Seems to be
271 the most common source of confusion.
272 - try to catch people naively blocking in an event callback.
273 - work around the perl filehandle bug issue in conjunction with
274 older common::sense (as indirectly pointed out by ZSystem).
275 - clarify the "not from signal handlers" section.
276
2775.2 Sun Oct 4 14:54:24 CEST 2009
278 - Coro::Storable destroyed the prototypes of the functions it wrapped.
279 - export rouse_cb and rouse_wait by default now.
280 - fix various prototype mismatches in Coro::AnyEvent and Coro::Handle.
281 - new method $state->swap_sv.
282 - added section on "windows process emulation" to the manpage,
283 after a not-so-fruitful (nor-friendly) "discussion" with chip
284 salzenberg (discussion implies arguments, but his only arguments
285 were ad-hominems, one wonders why he started it in the first
286 place). I hope this explains it well enough for him to understand,
287 and maybe well enough for others to understand.
288 - use common::sense everywhere now.
289 - idle callbacks are no longer supported, use idle coros instead.
290 - print a thread listing when a deadlock is detected.
291
2925.17 Sat Aug 22 23:09:31 CEST 2009
293 - work around a bug in the perl debugger causing crashes
294 when running under the debugger by marking _pool_handler as nodebug.
295 - speed up Coro::async considerably.
296 - try some hacks to get netbsd to work "more often" - their broken
297 setjmp/longjmp, ucontext *and* phtreads are really hard on Coro.
298 - convert Coro to AE 5.0 API.
299
3005.162 Tue Jul 28 04:04:03 CEST 2009
301 - perl 5.8.2 is now minimum requirement.
302 - skip t/19_handle.t on broken windows perls.
303
3045.161 Wed Jul 22 04:47:38 CEST 2009
305 - Coro::AnyEvent::poll could have a different prototype when EV was
306 used as backend (analyzed by Tatsuhiko Miyagawa).
307 - Coro::AnyEvent errornously initialised the event loop when loaded,
308 not on demand.
309 - try to workaround rare */t/01_unblock.t failures.
310
3115.16 Tue Jul 21 01:44:37 CEST 2009
312 - Coro::AnyEvent failed to hook into the event loop
313 when no threads had been readied between detecting
314 the event loop and actually running it.
315 - considerably speed up Coro::Select by taking avdantage
316 of AnyEvent > 4.8 and some other optimisations.
317 - implement paragraph readline mode in Coro::Handle
318 (based on patches by Zsbán Ambrus).
319 - replace WSAEINPROGRESS by WSAEWOULDBLOCK (reported
320 and analyzed by Yasuhiro MATSUMOTO).
321 - clarified libcoro license and copyright.
322 - someone stole my EXTRA_META!!!
323 - implement Coro::Select::patch_pp_sselect and it's brother,
324 for hardcode select overriding.
325
3265.151 Mon Jul 6 05:41:57 CEST 2009
327 - backport to windows process emulation code again (patch by
328 Yasuhiro MATSUMOTO).
329 - slightly update Coro::MakeMaker.
330
3315.15 Tue Jun 30 10:28:06 CEST 2009
332 - deprecate Coro::Socket, document how to get ipv6 support via
333 AnyEvent::Socket instead.
334 - implement signal->wait ($cb) interface, similar to semaphores.
335 - work around SvOK not supporting getmagic, so we have to getmagic
336 to test for undef :/ (reported by Matthias Waldorf).
337 - load Coro::AnyEvent in all modules using AnyEvent.
338 - work around perl corrupting our internal data structures,
339 reported by Tokuhiro Matsuno.
340 - enable per-coroutine real and cpu time gathering
341 (Coro::State::enable_times).
342
3435.14 Wed Jun 24 01:37:48 CEST 2009
344 - provide explicit functions to "cede" to the event loop in Coro::AnyEvent,
345 as this seems to have been a difficult concept (poll, sleep, idle,
346 idle_upto).
347 - add Coro::AnyEvent::readable/writable functions.
348 - clarify Coro::EV/Event/AnyEvent manpages.
349 - free per-thread global scalars in the thread calling ->cancel, to
350 avoid crashes when $_, $@ etc., are magical but some of those
351 had already been freed.
352 - "unexperimentalise" the callback interface for Coro::Semaphore.
353 - speed up ready queue management/context switching by using a linked
354 list instead of an array (~5-10%).
355 - implement "watch" command in Coro::Debug shells.
356 - for fun, implement time-slicing as an example in the manpage.
357 - if AnyEvent detects EV or Event, but we don't have Coro::EV or
358 Coro::Event, use the normal AnyEvent handling instead of dieing
359 (the same is true for Coro::Handle).
360 - properly document Coro::EV::timed_io_once.
361 - avoid unneccessary ->cancel calls in Coro::Handle.
362 - maybe make it work on mingw32 with win32 backend
363 (based on patch by Yasuhiro Matsumoto).
364
3655.132 Fri May 29 09:00:39 CEST 2009
366 - do not keep a reference to the argument itself in
367 Coro::Semaphore::guard, as it could change later.
368 - support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
369 should support a prepare callback.
370
3715.131 Mon Mar 16 23:20:37 CET 2009
372 - implement and document Coro->suspend, Coro->resume.
373 - fix Coro::Select implementation to not (often) close
374 the passed file descriptors (testcase provided by pippijn).
375
3765.13 Mon Dec 15 21:51:42 CET 2008
377 - EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
378 - don't set diehook to C<undef> but instead to NULL, to avoid
379 spurious warnings.
380 - fix a lot of bugs in Coro::SemaphoreSet.
381 - Coro::SemaphoreSet will less often create a semaphore needlessly.
382 - add Coro::SemaphoreSet::count and wait methods.
383 - take advantage of the new Guard module.
384 - deprecate Coro::guard.
385 - try to fix the dreaded 01_unblock tests once more. I hate it when
386 testsuites need more fixing than the code they are supposed to test.
387 - croak in more cases when a required callback isn't resolvable.
388 - fix some minor issues in Coro::State->call/eval.
389 - use current coroutine context instead of a temporary one
390 when temporarily switching to another coroutine.
391 - do not call C-level on_destroy handlers during global destruction,
392 to avoid needless segfaults.
393
3945.12 Sun Dec 7 13:30:38 CET 2008
395 - add default config for MirOS, which seems to be a bug-to-bug
396 compatible fork of openbsd ("world domination by releasing
397 openbsd cvs before the openbsd folks do it" or so :).
398 - free_padlist did destroy the names pad, not good, but didn't
399 seem to bother perl - this could fix issues such as eval ""
400 inside a function called from multiple coroutines.
401 - use a different method to detect destruction time.
402 - be more careful when freeing padlists just before global
403 destruction.
404 - fixed and expanded the call/cc example.
405 - renamed _terminate to _coro_run.
406 - new method Coro::Channel->shutdown.
407 - try pthreads on openbsd <4.4 (broken sigaltstack, will
408 pthreads fare better?).
409 - be less picky about destroying "a" running coroutine.
410
4115.11 Tue Nov 25 21:49:05 CET 2008
412 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
413 working code with failed assertions, introducing more bugs than
414 it fixes, requiring elaborate workarounds :(
415
4165.1 Mon Nov 24 08:54:59 CET 2008
417 - wrote a small introductory tutorial - Coro::Intro.
418 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
419 - Coro::Select did errornously dup the file descriptors
420 and didn't work with all AnyEvent backends.
421 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
422 LWP data transfers.
423 - disassociate c contexts from coro objects - this is agruably more
424 correct, but mostly allows sharing of cctxs between coro and state
425 objects, for added memory savings and speed increases.
426 - bumped $Coro::POOL_RSS up to 32kb by default.
427 - no longer set the optype to OP_CUSTOM, as B::* understandably
428 doesn't like this very much (and we *are* a type of entersub).
429 - implement state cloning, just to prove that call/cc can be done.
430 - automatically load Coro::AnyEvent in Coro::Handle.
431 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
432 do not have this method (and don't need it either).
433 - speed up generic anyevent methods in Coro::Handle by using rouse
434 callbacks.
435 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
436 others. It also makes the debugger happier, as you can trace
437 through the idle threads now.
438 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
439 - eg/event was pretty broken.
440 - better 5.8.6 compatibility.
441
4425.0 Thu Nov 20 10:35:05 CET 2008
443 - NEW ARCHITECTURE: use the latest 4.x version if you experience
444 stability issues.
13 - bump API version to 7 - all dependents must be recompiled. 445 - bump API version to 7 - all dependents must be recompiled.
446 - removed timed_* functions - they were not being used anyways
447 and should be replaced by a more generic mechanism -
448 and were annoying to support anyways :)
449 - removed SemaphoreSet's waiter method - use sem method instead.

19 would cause a deadlock (semaphore would get into a state where 455 would cause a deadlock (semaphore would get into a state where
20 it was available but waiters were waiting(. 456 it was available but waiters were still blocked).
457 - calling throw on a coroutine that is waiting for a semaphore will
458 no longer make it acquire the semaphore (and thus leak a count).
21 - perl's process emulation is now not even theoretically supported 459 - perl's process emulation is now not even theoretically supported
22 anymore. 460 anymore.
461 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
462 conversion of callback-style to blocking-style.
463 - new methods $coro->schedule_to and ->cede_to, to specifically
464 schedule or cede to a specific coroutine.
465 - new function Coro::Semaphore::wait.
466 - use named constants in Coro::Channel (Richard Hundt).
23 - directly patch the entersub opcode calling SLF functions (cede, 467 - directly patch the entersub opcode calling SLF functions (cede,

33 - use new SLF interface to massively speed up Coro::EV by roughly a factor 477 - use new SLF interface to massively speed up Coro::EV by roughly a
34 of two. 478 factor of two.
35 - removed timed_down and timed_guard functions - they were not being used
36 anyways and should be replaced by a more generic mechanism - and were
37 annoying to support anyways :
38 - used new SLF interface to massively speed up Coro::Semaphore by a factor 479 - used new SLF interface to massively speed up Coro::Semaphore by a
39 of three. 480 factor of three.
481 - used new SLF interface to speed up Coro::AIO by roughly a factor of
482 four and reduce its memory usage considerably.
483 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
484 for a nice speedup and vastly more correct behaviour. Also implement
485 a new method "sem" to get at the underlying semaphore object.
486 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
487 (in comparison) 20-40% speedup.
488 - used new SLF interface to reimplement Coro::Signal gaining
489 some unknown (because I was too lazy), but certain, speedup, and also
490 making signals reliable for the first time.
491 - used new SLF interface and other optimisations to speed up async_pool
492 by a factor of two. It also doesn't rely on perl's exception mechanism
493 to exit anymore. The overhead for terminating an async_pool, coro over
494 a normal async is now very small.
495 - sped up coroutine creation/destruction by 40%.
40 - forgot to include Coro/libcoro/README in the dist for all these years. 496 - forgot to include Coro/libcoro/README in the dist for all these years.

42 pthread_cond_wait isn't a cancellation point on freebsd). 498 pthread_cond_wait isn't a cancellation point on freebsd).
499 - use new rouse functions to speed up and simplify Coro::BDB.
500 - make "prefer perl native functions" work with threaded perls.
501 - condense Coro::Debug ps output, hint at v and w flags.
502 - (libcoro) lots of minor cleanups and portability improvements.
