1Revision history for Perl extension Coro. 1Revision history for Perl extension Coro.
2 2
3TODO: better (earlier) error messages on broken transfer's 3TODO: should explore PerlIO::coroaio (perl leaks like hell).
4TODO: maybe implement a default message channel, very much like Erlang's
5 actor model (which is cool in a lot of important aspects (failures!),
6 but very lacking in others (higher level ipc)).
4 7
53.3 8 TODO: Coro/Intro
9 - wrote a small introduction - Coro::Intro.
10 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
11 - Coro::Select did errornously dup the file descriptors
12 and didn't work with all AnyEvent backends.
13 - disassociate c contexts from coro objects - this is agruably more
14 correct, but mostly allows sharing of cctxs between coro and state
15 objects, for added memory savings and speed increases.
16 - bumped $Coro::POOL_RSS up to 32kb by default.
17 - no longer set the optype to OP_CUSTOM, as B::* understandably
18 doesn't like this very much (and we *are* a type of entersub).
19 - implement state cloning, just to prove that call/cc can be done.
20 - automatically load Coro::AnyEvent in Coro::Handle.
21 - better 5.8.6 compatibility.
22
235.0 Thu Nov 20 10:35:05 CET 2008
24 - NEW ARCHITECTURE: use the latest 4.x version if you experience
25 stability issues.
26 - bump API version to 7 - all dependents must be recompiled.
27 - removed timed_* functions - they were not being used anyways
28 and should be replaced by a more generic mechanism -
29 and were annoying to support anyways :)
30 - removed SemaphoreSet's waiter method - use sem method instead.
31 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
32 - async_pool did free a scalar value twice
33 ("Attempt to unreference...").
34 - fix a longstanding bug where calling terminate on a coro that
35 was waiting for a semaphore that was just becoming available
36 would cause a deadlock (semaphore would get into a state where
37 it was available but waiters were still blocked).
38 - calling throw on a coroutine that is waiting for a semaphore will
39 no longer make it acquire the semaphore (and thus leak a count).
40 - perl's process emulation is now not even theoretically supported
41 anymore.
42 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
43 conversion of callback-style to blocking-style.
44 - new methods $coro->schedule_to and ->cede_to, to specifically
45 schedule or cede to a specific coroutine.
46 - new function Coro::Semaphore::wait.
47 - use named constants in Coro::Channel (Richard Hundt).
48 - directly patch the entersub opcode calling SLF functions (cede,
49 transfer and so on). this does speed up context switching, but
50 more importanly, it frees us from the hardcoded behaviour of
51 entersub, so we might actually be able to return something from
52 those functions and atcually create new ones.
53 - take advantage of __builtin_frame_address on gcc.
54 - expose THX in coroapi (not sure whether this was a wise decision,
55 as "threaded" perls are running at half speed anyways).
56 - implement execute_slf (schedule-like-function) interface that makes
57 it possible to implement schedule-like-functions in XS.
58 - use new SLF interface to massively speed up Coro::EV by roughly a
59 factor of two.
60 - used new SLF interface to massively speed up Coro::Semaphore by a
61 factor of three.
62 - used new SLF interface to speed up Coro::AIO by roughly a factor of
63 four and reduce its memory usage considerably.
64 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
65 for a nice speedup and vastly more correct behaviour. Also implement
66 a new method "sem" to get at the underlying semaphore object.
67 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
68 (in comparison) 20-40% speedup.
69 - used new SLF interface to reimplement Coro::Signal gaining
70 some unknown (because I was too lazy), but certain, speedup, and also
71 making signals reliable for the first time.
72 - used new SLF interface and other optimisations to speed up async_pool
73 by a factor of two. It also doesn't rely on perl's exception mechanism
74 to exit anymore. The overhead for terminating an async_pool, coro over
75 a normal async is now very small.
76 - sped up coroutine creation/destruction by 40%.
77 - forgot to include Coro/libcoro/README in the dist for all these years.
78 - work around a freebsd pthreads bug (manual testcancel is required as
79 pthread_cond_wait isn't a cancellation point on freebsd).
80 - use new rouse functions to speed up and simplify Coro::BDB.
81 - make "prefer perl native functions" work with threaded perls.
82 - condense Coro::Debug ps output, hint at v and w flags.
83 - (libcoro) lots of minor cleanups and portability improvements.
84
854.914 Wed Nov 19 12:54:18 CET 2008
86 - fix a disastrous bug in the readline optimisation
87 introduced in 4.801.
88
894.913 Sat Nov 15 07:58:28 CET 2008
90 - async_pool did free a scalar value twice
91 ("Attempt to unreference...").
92
934.912 Thu Nov 13 18:31:23 CET 2008
94 - minor cleanups.
95 - use much larger stacks on linux and perl < 5.8.8.
96 - Coro::Debug::new_unix_server did not unlink the socket
97 when destroyed.
98
994.911 Tue Nov 11 04:26:17 CET 2008
100 - "port" to threaded perls.
101
1024.91 Mon Nov 10 05:36:38 CET 2008
103 - the ->throw exception object no longer leaks.
104 - creating a new cctx leaked a scopestack entry (memleak).
105 - new coroutines didn't get created with a zero flags field
106 (unknown impact).
107 - calling ->throw on a not-yet-started coroutine should now work
108 instead of being ignored.
109 - ->throw is now supported on Coro::State objects.
110 - clean up cctx creation code a bit.
111 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
112
1134.9 Sat Nov 8 17:45:27 CET 2008
114 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
115 - (libcoro) no longer leak threads in the experimental pthread backend,
116 also speed it up considerably.
117 - (libcoro) do not rely on makecontext passing void *'s unscathed.
118 - fix compiletime dependencies on libcoro in the Makefile.
119 - cctx_count wasn't always updated properly.
120 - Coro::State::cctx_stacksize wasn't applied correctly.
121 - new function Coro::State::cctx_max_idle.
122 - the default max number of idle C contexts is now 4.
123 - (libcoro) try harder to get _setjmp/_longjmp.
124 - (libcoro) cleanup and extend the libcoro API to officially
125 allow the creation of empty source contexts.
126 - very experimental workaround for the totally broken netbsd platform.
127 - tried to hack around openbsd bugs.
128
1294.804 Wed Nov 5 16:36:00 CET 2008
130 - Coro::Debug::new_unix_server would not create a non-blocking listening
131 socket, sometimes causing freezes.
132 - (libcoro) fix misaligned stack points for setjmp and assembly
133 methods, which can cause crashes on x86/x86_64 with a sufficiently
134 aggressive compiler.
135 - new function: Coro::Debug::new_tcp_server.
136 - move ->throw into the Coro class because it only works on coro objects.
137
1384.803 Mon Nov 3 17:16:12 CET 2008
139 - (libcoro) use a global asm statement to become independent of gcc
140 otpimisations for CORO_ASM (thanks to pippijn for the idea).
141 - try to workaround yet another broken bsd, this time dragonfly.
142
1434.802 Thu Oct 30 10:56:12 CET 2008
144 - support -fno-omit-frame-pointer on x86 with the assembly method.
145 - tune 01_unblock.t tests a bit.
146
1474.801 Wed Oct 22 18:33:37 CEST 2008
148 - improve readline speed for very long "lines".
149 - backport to 5.8.8.
150
1514.8 Thu Oct 2 13:34:40 CEST 2008
152 - new function Coro::AIO::aio_wait.
153 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
154 - greatly speed up and reduce memory usage of Coro::AIO requests.
155 - implement some other µ-optimisations.
156
1574.749 Mon Sep 29 14:40:12 CEST 2008
158 - port to slow and broken pseudo-threaded perls. (courtesy pippijn).
159
1604.748 Sat Sep 27 14:03:19 CEST 2008
161 - implement, but do not document, PerlIO::cede(granularity).
162 - Coro::Storable forgot to wrap Storable::pstore.
163 - work around the multitude of leaks and memory corruption
164 bugs in PerlIO::via by using our own C-level perliol. As a side
165 effect, Coro::Storable is now much, much, much faster.
166
1674.747 Tue Sep 23 01:59:41 CEST 2008
168 - fix a per-cv memleak (one empty array was leaked per
169 code reference).
170 - avoid a crash in coro->call|rss when the coroutine was already
171 destroyed (most noticably when using Coro::Debug::ps :)
172 - also protect *Storable::FILE.
173 - push up default storable granularity to 20ms.
174
1754.746 Sun Sep 21 03:22:20 CEST 2008
176 - be more insistent on locking Storable against reentrancy
177 in Coro::Storable.
178 - move swap_def?v and throw to Coro::State, as documented.
179
1804.745 Thu Jul 24 00:14:38 CEST 2008
181 - remove debugging code related to MgPV_nolen_const, also try to
182 make it compile with perl 5.8.6 (yes, apple apparently loves
183 outdated software). Reported by John S.
184
1854.744 Tue Jul 8 22:06:35 CEST 2008
186 - correctly provide default DIE/WARN handlers as documented.
187 - also overwrite PL_vtbl_sigelem.svt_clear, even though current
188 implementations inside perl work fine for us.
189
1904.743 Mon Jun 16 00:21:57 CEST 2008
191 - when using Coro::EV without running EV::loop it could
192 result in busy-waiting for events, this has been fixed.
193 - reduce codesize and improve performance by using EV_DEFAULT_UC.
194
1954.742 Sat May 31 14:10:21 CEST 2008
196 - implement a workaround for (some) perl <5.8.8 versions.
197 - require EV 3.3+.
198
1994.741 Fri May 30 23:33:09 CEST 2008
200 - tell netbsd how utterly broken their imitation of an OS is
201 and refuse to build by default if pthreads are in use.
202 - switch to "s" method on all bsd's by default, as their ucontext
203 stuff seems just too broken.
204 - fix a bug in Coro::Select.
205
2064.74 Thu May 29 20:05:31 CEST 2008
207 - do not test Coro::LWP for lack of dependencies.
208 - do not test Coro::Select for lack of working perls.
209
2104.73 Thu May 29 2008
211 - fix a bug in Coro::EV which would cause it to block despite
212 there being runnable coroutines.
213 - sprinkle "no warnings" freely over everything, also suppress
214 warnings for some other modules.
215 - fix typo in WSAEWOULDBLOCK.
216
2174.72 Sun May 25 05:14:36 CEST 2008
218 - tweak META.yaml a bit, unfortunately, there is no documented way
219 to have optional dependencies with CPAN. doh :(
220 - avoid running some tests on windows because they would fail due to
221 perl bug (broken fork, broken pipes...).
222 - work around perl on windows bugs where perl returns undocumented
223 error codes for sysread, syswrite etc. by taking advantage
224 of AnyEvent's workaround for that problem.
225 - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
226 a common perl implementation bug on windows.
227 - use unix domain sockets in testsuite to work around
228 common perl implementation bugs on widows (they are emulated by
229 tcp sockets on windows. ugh.)
230
2314.71 Sat May 24 20:01:27 CEST 2008
232 - fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
233 - take advantage of async name resolution of AnyEvent::Util.
234 - work around brutal inet_aton override in Coro::LWP.
235 - take advantage of the readyhook in Coro::EV, for smoother
236 scheduling.
237
2384.7 Sun May 11 00:32:19 CEST 2008
239 - completely reworked the Coro manpage.
240 - added Coro::AnyEvent, generic event loop integration.
241 - implement cancel, ready and kill commands in Coro::Debug.
242 - document find_coro in Coro::Debug.
243 - incompatible change: rename has_stack to has_cctx.
244 - Coro::AIO and Coro::BDB no longer force event model detection,
245 use AnyEvent::AIO and AnyEvent::BDB.
246
2474.6 Sat Apr 26 10:05:14 CEST 2008
248 - INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
249 by the Coro module. It was a mistake to have it in the first place.
250 - (experimental) support for activestate perl 5.10 (method "w").
251 - (experimental) support for strawberry perl (method "a").
252 - coro_sigelem_set did not return a value although it had to,
253 actual impact unknown.
254
2554.51 Mon Apr 14 13:28:27 CEST 2008
256 - make it compile again on 5.8.
257
2584.50 Thu Apr 10 09:43:17 CEST 2008
259 - I did it twice! (see 4.49).
260
2614.49 Sun Apr 6 21:23:31 CEST 2008
262 - grr, instead of compiling the recent changes on 5.10 only they
263 were compiled on 5.8 only.
264
2654.48 Sun Apr 6 20:36:46 CEST 2008
266 - allow coroutine switches during eval's under 5.10.x, as it seems
267 the parser is a per-interpreter option now, so this is safe
268 (this might fix the odd crashing bug).
269 - drop support for 5.9.x versions: they are dead, jim.
270
2714.47 Sun Apr 6 00:37:52 CEST 2008
272 - force cctx allocation on API calls: we know we need to force one
273 and gcc actually manages to confuse our heuristic nowadays,
274 leading to crashes and worse.
275 - document force_cctx.
276
2774.46 Fri Apr 4 22:05:43 CEST 2008
278 - upgrade libcoro, resulting in pthread-backend (which was only created
279 to fulfill the rules of the programming languages shootout).
280
2814.45 Thu Mar 13 11:55:36 CET 2008
282 - fix a file leaking bug in eg/mhyttpd that would allow
283 downloading of any file (reported by oesi).
284 - fix deadlock bug in Coro::Channel (reported by Richard Hundt)
285 (also add testcase).
286 - support Broadcast option in Coro::Socket (patch by Richard Hundt,
287 apparently having loads of fun with that).
288 - implement $state->swap_defsv, ->swap_defav and document ->throw.
289
2904.4 Wed Feb 13 16:44:29 CET 2008
291 - only assume .cfi pseudo isns exist on GNU/Linux.
292 - add get_timed method to Coro::Channels.
293 - fixed Coro::Debug manpage.
294 - perl 5.11 compatbility improvement based on patch by
295 Andreas König.
296
2974.37 Sun Jan 20 11:25:23 CET 2008
298 - soften the check for an active parser for perl 5.10 (avoiding
299 "Coro::State::transfer called while parsing" in many cases).
300
3014.36 Sun Jan 13 10:53:56 CET 2008
302 - reset diehook when terminating from an async_pool as to not
303 trigger any __DIE__ handlers.
304
3054.35 Sun Jan 13 04:14:13 CET 2008
306 - "bt" debug command now displays any exceptions
307 from longmess and also skips the innermost
308 stackframes, giving more useufl output.
309 - allow backtraces in coroutines blocked in Coro::EV,
310 at a <1% speed hit.
311 - handle localising of $SIG{__WARN__} and __DIE__
312 properly (with a proper amount of dirty hacking).
313
3144.34 Sat Dec 22 17:49:53 CET 2007
315 - upgrade to EV version 2.0 API.
316
3174.33 Mon Dec 17 08:36:12 CET 2007
318 - make Coro::AIO etc. loadable in the absence of EV.
319
3204.32 Mon Dec 17 07:46:02 CET 2007
321 - majorly improved Coro::Handle's performance with Coro::EV.
322 - implemented the until now mythical Coro::BDB module.
323 - specialcase EV in Coro::AIO and Coro::BDB for extra speed.
324
3254.31 Wed Dec 5 12:32:39 CET 2007
326 - remove warn statement form Coro::Util.
327
3284.3 Tue Dec 4 20:33:14 CET 2007
329 - calls to the idle function could cause stack corruption
330 when the stack changed.
331 - do no longer rely on the presence of EV::DNS if EV is used
332 (because it is gone), but instead take avdantage of EV::ADNS
333 if available.
334 - add ($) prototypes to all functions in Coro::Storable.
335 - use a conventional (safer) idle callback in Coro::EV.
336 - do accept quickly in Coro::Debug to avoid endless loops.
337
3384.22 Fri Nov 30 16:04:04 CET 2007
339 - really use optimised versions for Event and EV in Coro::Util
340 and Coro::Handle.
341
3424.21 Sun Nov 25 10:48:59 CET 2007
343 - fix a spurious memory read.
344 - Coro::EV no longer keeps the eventloop "alive".
345
3464.2 Fri Nov 9 20:47:05 CET 2007
347 - enable/disable tracing from a new coroutine, not a pooled one.
348 - fix a memleak in Coro::Event.
349 - removed killall call from fork_eval.
350 - made sure store_fd is already loaded so that fork_eval
351 does not have to parse autoload in each subprocess.
352 - only use assembly method if -O switch is in $Config{optimize}.
353 - add (optional) Coro::EV module, so far the best event loop module
354 directly supported by Coro.
355 - if the event model is EV, use EV::DNS to resolve
356 stuff in Coro::Util.
357 - don't get confused by multiple event notifications in Coro::Handle.
358 - initial support for EV (libevent interface).
359 - require Event and EV using configure_requires, to force their existance.
360
3614.13 Wed Oct 24 07:26:45 CEST 2007
362 - add Coro::Storable::blocking_thaw.
363 - use a vastly more complicated technique to localise
364 $SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
365 - use a coroutine for the idle callback Coro::Event,
366 instead of running Event in the current coroutine context.
367 This also catches recursive invocations.
368 - actually report fork errors in gethostbyname and inet_aton.
369
3704.11 Thu Oct 11 02:40:24 CEST 2007
371 - port to threaded perls.
372
3734.1 Thu Oct 11 02:38:16 CEST 2007
374 - incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
375 be local to each coro (see Coro::State).
376 - incompatible change: for very deep reasons, cede and cede_notself
377 cannot return anything, so nothing will be returned.
378 - possibly bring back 5.10 compatibility (untested).
379 - work around stupid (and wrong) warning on 5.10 :(.
380 - overlay the saved state over the context stack. This saves
381 a few hundred bytes per coroutine on average and also
382 speeds up context switching a bit.
383 - further tune default stack sizes.
384 - (more) correctly calculate stack usage in coro_rss.
385 - Coro::Storable::blocking_* did not properly lock
386 resulting in races between coroutines.
387 - added Coro::Storable::guard.
388 - stopping to trace a coroutine could destroy the cctx of
389 an unrelated coroutine.
390 - explain the relationship between Perl and C coroutines in
391 more detail in Coro::State.
392 - Coro::Util::inet_aton did not short-circuit dotted quad forms,
393 causing a fork per resolve. This also affected Coro::Socket.
394 - switch to a separate stack in $coro->call/eval to avoid
395 invalidating pointers.
396
3974.03 Sat Oct 6 21:24:00 CEST 2007
398 - added Coro::throw method.
399 - minor code cleanups.
400
4014.02 Sat Oct 6 02:36:47 CEST 2007
402 - fix a very minor per-coroutine memleak (a single codereference).
403 - fixed a bug where the currently in-use c context would be freed
404 prematurely (can happen only when programs change the stacksize
405 or use tracing).
406 - tracing can no longer keep a coro alive after it terminated.
407 - do static branch prediction in the common path for gcc. gives
408 about 2-5% speed improvement here.
409
4104.01 Fri Oct 5 22:10:49 CEST 2007
411 - instead of recreating *a* standard output handle we simply
412 use STDOUT, which is faster and hopefully more robust.
413
4144.0 Fri Oct 5 12:56:00 CEST 2007
415 - incompatibly changed Coro::Storable::freeze.
416 - major new feature: added Coro::Debug, for interactive coroutine
417 debugging, tracing and much more.
418 - major bug fix: unbelievable, but true: $_, $/ and many other
419 "saved" variables actually weren't being saved. This has been fixed,
420 of course, while increasing performance while losing all the save
421 flags.
422 - save flags are gone, and all the api functions dealing with them.
423 - added Coro::Semaphore::adjust.
424 - added Coro::Util::fork_eval.
425 - added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
426 - added Coro::killall.
427 - reduce initial stack sizes to allow for "micro-coroutines".
428 - better async_pool resource management, moved parts of async_pool
429 handling to XS (major speed improvement).
430 - actually croak before modifying important data structures.
431 - refuse to transfer while compiling.
432 - possibly support eval EXPR better now.
433 - enable assembly per default on linux+bsd x86+amd64.
434 - all internal members were renamed _something for easier subclassing.
435 - many minor tweaks.
436
4373.63 Wed May 16 14:10:06 CEST 2007
438 - implement handcoded assembly for x86/amd64 SVR ABI.
439
4403.62 Fri Apr 27 21:36:06 CEST 2007
441 - upgrade libcoro (which might set unwind info correctly).
442 - change default on linux to setjmp/longjmp.
443
4443.61 Thu Apr 19 12:36:18 CEST 2007
445 - Coro::Storable caused an endless loop when thawing invalid
446 pst's sometimes.
447 - use a Semaphore in Coro::Storable, as Storable doesn't
448 seem to be reentrant (although it is documented to
449 be threadsafe...).
450 - fix Coro::Signal to bring back the original unreliable
451 but stateful semantics.
452 - fixed a lot of typos in Coro.pm (patch submitted by David
453 Steinbrunner, which applied flawlessly).
454
4553.6 Sat Apr 14 17:13:31 CEST 2007
456 - added some bugfixes to get eg/myhttpd working again.
457 - added Coro::Storable for often-cede'ing freeze/thaw.
458 - try to do a clean exit when a coroutine calls exit
459 (EXPERIMENTAL).
460 - got rid of indirect call through _coro_init.
461 - updated the partly antique examples in eg/ to
462 work again and be a bit less magic, too.
463 - fixed Coro::Signal semantics to work as documented again.
464
4653.55 Sun Mar 25 01:20:47 CET 2007
466 - add SAVE_DEFFH to save the default filehandle and enable
467 it by default.
468 - finally move socket-operations from Coro::Socket to Coro::Handle
469 to be able to unblock foreign sockets.
470 - add Coro::State::save_also and guarded_save.
471 - add count accessor to Coro::Semaphore.
472 - add Coro::State::cctx_stacksize.
473 - just for the fun of it, do not rely on implicit context,
474 which can dramatically improve performance, but people
475 using windows-process-emulation perls do not care much about
476 performance.
477
4783.51 Sun Mar 4 14:18:04 CET 2007
479 - fixed a problem when you weakened references to Coro::State's
480 (patch by Yuval Kogman).
481
4823.501 Wed Feb 28 12:44:07 CET 2007
483 - rename some global symbols as macosx from hell redefines
484 them without asking.
485
4863.5 Tue Feb 13 20:22:53 CET 2007
487 - do AnyEvent model detection earlier, avoiding problems
488 caused by first using AnyEvent and later Coro::Event.
489 - implement and document Coro::Event event objects.
490 - fix a potential problem in Coro::Event causing crashes.
491 - initialise PL_comppad when creating a new coroutine,
492 avoids crashes on early coro destruction.
493
4943.41 Mon Jan 22 19:19:49 CET 2007
495 - readline on Coro::Handle did not support undefined $/,
496 nor did it deliver partial lines on EOF or error.
497 - implement malloc fallback for stack allocation because
498 stupid broken idiotic OSX has a stupid broken
499 idiotic fits-the-whole-os mmap "implementation" and
500 my dick feels longer if Coro is portable even to
501 obsolete platforms.
502
5033.4 Fri Jan 19 21:52:54 CET 2007
504 - remove t/09_timer.t, as it isn't really testing much
505 but was rather flaky in practise.
506 - async_pool coro would keep arguments and callback alive until
507 it was reused.
508 - cancellation of a coroutine could cause spurious idle calls
509 in cede_notself.
510
5113.3 Sat Jan 6 03:45:00 CET 2007
6 - implement $coro->on_destroy. 512 - implement $coro->on_destroy.
7 - Coro::Event blocking semantics have been changed, 513 - Coro::Event blocking semantics have been changed,
8 documented and - hopefully - improved. 514 documented and - hopefully - improved.
9 - fix nice adding, not subtracting, from priority. 515 - fix nice adding, not subtracting, from priority.
10 - fix ->prio and api_is_ready (patch by Mark Hinds). 516 - fix ->prio and api_is_ready (patch by Mark Hinds).
11 - fixed an assert ("... == prev__cctx->idle_te") 517 - fixed an assert ("... == prev__cctx->idle_te")
12 that could errronously trigger. 518 that could errronously trigger.
519 - fix various large and small memleaks.
520 - use a (hopefully) more stable cancel implementation
521 that immediately frees the coroutine data.
522 - cede/cede_notself return a status now.
523 - added Coro::guard function.
524 - added a global coroutine pool for jobs (on my machine,
525 I can create and execute 48k simple coros/s with async,
526 and 128k coros with async_pool).
527 - Coro::AIO now uses the coroutine priority as io priority.
