3	TODO: better (earlier) error messages on broken transfer's	3	TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.
4	TODO: destroy gets only called on cancel: fix(?)	4	TODO: maybe implement a default message channel, very much like Erlang
		5	(which is cool in a lot of important aspects (failures!),
		6	but very lacking in others (higher level ipc)).

6	3.52	8	4.2 Fri Nov 9 20:47:05 CET 2007
		9	- enable/disable tracing from a new coroutine, not a pooled one.
		10	- fix a memleak in Coro::Event.
		11	- removed killall call from fork_eval.
		12	- made sure store_fd is already loaded so that fork_eval
		13	does not have to parse autoload in each subprocess.
		14	- only use assembly method if -O switch is in $Config{optimize}.
		15	- add (optional) Coro::EV module, so far the best event loop module
		16	directly supported by Coro.
		17	- if the event model is EV, use EV::DNS to resolve
		18	stuff in Coro::Util.
		19	- don't get confused by multiple event notifications in Coro::Handle.
		20	- initial support for EV (libevent interface).
		21	- require Event and EV using configure_requires, to force their existance.
		22
		23	4.13 Wed Oct 24 07:26:45 CEST 2007
		24	- add Coro::Storable::blocking_thaw.
		25	- use a vastly more complicated technique to localise
		26	$SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
		27	- use a coroutine for the idle callback Coro::Event,
		28	instead of running Event in the current coroutine context.
		29	This also catches recursive invocations.
		30	- actually report fork errors in gethostbyname and inet_aton.
		31
		32	4.11 Thu Oct 11 02:40:24 CEST 2007
		33	- port to threaded perls.
		34
		35	4.1 Thu Oct 11 02:38:16 CEST 2007
		36	- incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
		37	be local to each coro (see Coro::State).
		38	- incompatible change: for very deep reasons, cede and cede_notself
		39	cannot return anything, so nothing will be returned.
		40	- possibly bring back 5.10 compatibility (untested).
		41	- work around stupid (and wrong) warning on 5.10 :(.
		42	- overlay the saved state over the context stack. This saves
		43	a few hundred bytes per coroutine on average and also
		44	speeds up context switching a bit.
		45	- further tune default stack sizes.
		46	- (more) correctly calculate stack usage in coro_rss.
		47	- Coro::Storable::blocking_* did not properly lock
		48	resulting in races between coroutines.
		49	- added Coro::Storable::guard.
		50	- stopping to trace a coroutine could destroy the cctx of
		51	an unrelated coroutine.
		52	- explain the relationship between Perl and C coroutines in
		53	more detail in Coro::State.
		54	- Coro::Util::inet_aton did not short-circuit dotted quad forms,
		55	causing a fork per resolve. This also affected Coro::Socket.
		56	- switch to a separate stack in $coro->call/eval to avoid
		57	invalidating pointers.
		58
		59	4.03 Sat Oct 6 21:24:00 CEST 2007
		60	- added Coro::throw method.
		61	- minor code cleanups.
		62
		63	4.02 Sat Oct 6 02:36:47 CEST 2007
		64	- fix a very minor per-coroutine memleak (a single codereference).
		65	- fixed a bug where the currently in-use c context would be freed
		66	prematurely (can happen only when programs change the stacksize
		67	or use tracing).
		68	- tracing can no longer keep a coro alive after it terminated.
		69	- do static branch prediction in the common path for gcc. gives
		70	about 2-5% speed improvement here.
		71
		72	4.01 Fri Oct 5 22:10:49 CEST 2007
		73	- instead of recreating a standard output handle we simply
		74	use STDOUT, which is faster and hopefully more robust.
		75
		76	4.0 Fri Oct 5 12:56:00 CEST 2007
		77	- incompatibly changed Coro::Storable::freeze.
		78	- major new feature: added Coro::Debug, for interactive coroutine
		79	debugging, tracing and much more.
		80	- major bug fix: unbelievable, but true: $_, $/ and many other
		81	"saved" variables actually weren't being saved. This has been fixed,
		82	of course, while increasing performance while losing all the save
		83	flags.
		84	- save flags are gone, and all the api functions dealing with them.
		85	- added Coro::Semaphore::adjust.
		86	- added Coro::Util::fork_eval.
		87	- added Coro::Storable::{nfreeze,blocking_{freeze,nfreeze}}.
		88	- added Coro::killall.
		89	- reduce initial stack sizes to allow for "micro-coroutines".
		90	- better async_pool resource management, moved parts of async_pool
		91	handling to XS (major speed improvement).
		92	- actually croak before modifying important data structures.
		93	- refuse to transfer while compiling.
		94	- possibly support eval EXPR better now.
		95	- enable assembly per default on linux+bsd x86+amd64.
		96	- all internal members were renamed _something for easier subclassing.
		97	- many minor tweaks.
		98
		99	3.63 Wed May 16 14:10:06 CEST 2007
		100	- implement handcoded assembly for x86/amd64 SVR ABI.
		101
		102	3.62 Fri Apr 27 21:36:06 CEST 2007
		103	- upgrade libcoro (which might set unwind info correctly).
		104	- change default on linux to setjmp/longjmp.
		105
		106	3.61 Thu Apr 19 12:36:18 CEST 2007
		107	- Coro::Storable caused an endless loop when thawing invalid
		108	pst's sometimes.
		109	- use a Semaphore in Coro::Storable, as Storable doesn't
		110	seem to be reentrant (although it is documented to
		111	be threadsafe...).
		112	- fix Coro::Signal to bring back the original unreliable
		113	but stateful semantics.
		114	- fixed a lot of typos in Coro.pm (patch submitted by David
		115	Steinbrunner, which applied flawlessly).
		116
		117	3.6 Sat Apr 14 17:13:31 CEST 2007
		118	- added some bugfixes to get eg/myhttpd working again.
		119	- added Coro::Storable for often-cede'ing freeze/thaw.
		120	- try to do a clean exit when a coroutine calls exit
		121	(EXPERIMENTAL).
		122	- got rid of indirect call through _coro_init.
		123	- updated the partly antique examples in eg/ to
		124	work again and be a bit less magic, too.
		125	- fixed Coro::Signal semantics to work as documented again.
		126
		127	3.55 Sun Mar 25 01:20:47 CET 2007
		128	- add SAVE_DEFFH to save the default filehandle and enable
		129	it by default.
		130	- finally move socket-operations from Coro::Socket to Coro::Handle
		131	to be able to unblock foreign sockets.
		132	- add Coro::State::save_also and guarded_save.
7	- add count accessor to Coro::Semaphore.	133	- add count accessor to Coro::Semaphore.
