		11	6.37 Tue Mar 4 13:27:33 CET 2014
		12	- sigh, removed leftover debugging code from debugging a
		13	perl bug, of all things.
		14
		15	6.36 Tue Mar 4 07:11:59 CET 2014
		16	- semaphores would not clear the destroy hook when interrupted
		17	by ->throw, causing segfaults or worse.
		18	- ->throw on a thread waiting for a semaphore did not acquire
		19	the semaphore, but also didn't wake up other waiters,
		20	possibly causing a deadlock.
		21	- "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
		22	to report a full stacktrace, which should help find out
		23	where the actual call is.
		24	- "atomically" destroy data in slf_destroy, because it is
		25	the right thing to do, just in case.
		26	- disable ecb.h libm dependency, to compile on ancient systems
		27	or under adverse conditions.
		28
		29	6.33 Mon Nov 18 11:26:27 CET 2013
		30	- do not crash when freeing padlists with holes (in 5.18).
		31	- tentative SVt_BIND 5.19 port/fix.
		32
		33	6.32 Tue Nov 5 15:35:35 CET 2013
		34	- use a new algorithm to derive padlists for perl 5.18. The old
		35	one could lead to 0-pointer accesses inside perl (reported
		36	by Darin McBride).
		37
		38	6.31 Thu May 9 07:39:48 CEST 2013
		39	- Coro::AIO requests would crash if the thread was ready'd
		40	while the request was ongoing.
		41
		42	6.29 Wed May 8 02:55:18 CEST 2013
		43	- when an on_destroy handler destructs the coro currently being
		44	destructed a perl scalar could be accessed after being freed,
		45	likely causing a crash.
		46
		47	6.28 Wed Mar 6 06:58:02 CET 2013
		48	- clean remnants of existing __DIE__ and __WARN__ handlers so
		49	they lose their magic and will not cause segfaults later
		50	(testcase by Andrey Sagulin).
		51	- improved Coro::State documentation a bit.
		52	- Coro::Debug::command now flushes the output.
		53	- add hack detection code for x32 abi, because the braindead slugs
		54	who designed that made it look exactly like x86_64 without
		55	providing proper compile time symbols to test for it. as a result,
		56	this detection cannot work reliably.
		57	- valgrind stack registering was broken.
		58	- do not rely on Time::HiRes anymore in Coro::Debug.
		59
		60	6.23 Fri Dec 7 23:36:37 CET 2012
		61	- use experimental fiber implementation on native windows
		62	perls.
		63	- use sizeof (void *) as multiplication factor for stack sizes,
		64	to accomodate the totally braindamaged microsoft 64 bit "os".
		65	- changed verifier host from win2k-ap510-32 to win7-sp516-32/64.
		66	activeperl 5.16 crashes when PerlIO_define_layer is called due
		67	to some bug in the perl dll, strawberry perl at least passes
		68	the testsuite.
		69	- implement Coro::Handle->peeraddr/host/port, for slightly
		70	improved compatibility with LWP.
		71	- implement 5.17 compatibility by almost blindly applying a
		72	good-looking patch by Father Chrysostomos.
		73	- move stack management functions into libcoro 3.
		74	- libcoro version 3 "released".
		75	- support magic values as timed_io_once args.
		76	- recommend AnyEvent 7+ or EV 4+, also require EV
		77	version 4 or newer for Coro::EV.
		78
		79	6.10 Tue Oct 9 01:14:27 CEST 2012
		80	- updated ecb.h, it had a typo that caused it to not compile on many
		81	big endian systems (reported by many people).
		82	- disable memory fences in ecb.h to improve portability.
		83
		84	6.09 Sat Oct 6 23:25:02 CEST 2012
		85	- Coro::EV I/O watchers were not interruptible by exceptions
		86	(Coro::State::throw) (testcase by sten).
		87	- ->throw now puts threads into the ready queue, as this seems to
		88	be expected by existing code, and code that doesn't cope with spurious
		89	wakeups needs fixing anyway.
		90	- use fd -1 in mmap.
		91	- cast I32 to int in error message printf.
		92	- warn about broken so-called "hardened" kernels.
		93
		94	6.08 Fri Apr 13 12:05:47 CEST 2012
		95	- be more aggressive about exiting like perl does - formerly,
		96	exiting from the non-main thread would not execute END blocks.
		97
		98	6.07 Fri Nov 11 21:21:48 CET 2011
		99	- work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
		100	- update ecb.h.
		101
		102	6.06 Mon Aug 8 23:59:48 CEST 2011
		103	- cygwin unfortunately patches the stack at runtime, so we use the pthreads
		104	backend, which is an order of magnitude slower. unfortunately, cygwins
		105	pthread implementation isn't very complete either, so allocate the stack
		106	twice just to be sure.
		107	(note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
		108	in its ithreaded perl - best recompile cygwin and use the 'w'indows
		109	backend for much better performance. also disable ithreads for
		110	even better performance...).
		111
		112	6.05 Thu Aug 4 21:36:36 CEST 2011
		113	- blush, condvar values would not be propagated from send to recv anymore
		114	(reported by Chip Salzenberg).
		115	- use exponential increase for the readline buffer length in
		116	Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
		117
		118	6.04 Wed Aug 3 17:15:45 CEST 2011
		119	- use even more efficient and more compatible condvars for
		120	compatibility to AnyEvent 6.x :)
		121	- more inconsequential ecb.h updates.
		122
		123	6.03 Wed Aug 3 11:41:30 CEST 2011
		124	- change how Coro patches AnyEvent condvars for compatibility to
		125	AnyEvent 6.x.
		126	- update ecb.h, to no longer include <pthread.h> in case WinNT.h
		127	hasn't been included.
		128
		129	6.02 Wed Jul 13 04:35:19 CEST 2011
		130	- "improve portability to Gentoo" - gentoo manages to put perl variables
		131	in memory areas that are farther than 2gb apart, which the jit couldn't
		132	handle and barfed. now it's just a bit slower on gentoo and similar
		133	systems.
		134
		135	6.01 Sun Jul 3 12:31:14 CEST 2011
		136	- workarounds are good, but the test for whether pthreads are used
		137	was not good. thisone should be better.
		138	- check differently whether gcc generates cfi instructions itself.
		139
