8 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
9 backend, which is an order of magnitutde slower. unfortunately, cygwins
10 pthread implementation isn't very complete either, so allocate the stack
11 twice just to be sure.
12 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
13 in its ithreaded perl - best recompile cygwin and use the 'w'indows
14 backend for much better performance. also disable ithreads for
15 even better performance...).

18 - blush, condvar values would not be propagated from send to recv anymore
19 (reported by Chip Salzenberg).
20 - use exponential increase for the readline buffer length in
21 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.

24 - use even more efficient and more compatible condvars for
25 compatibility to AnyEvent 6.x :)
26 - more inconsequential ecb.h updates.

286.03 Wed Aug 3 11:41:30 CEST 2011
29 - change how Coro patches AnyEvent condvars for compatibility to
30 AnyEvent 6.x.
31 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
32 hasn't been included.

35 - "improve portability to Gentoo" - gentoo manages to put perl variables
36 in memory areas that are farther than 2gb apart, which the jit couldn't
37 handle and barfed. now it's just a bit slower on gentoo and similar
38 systems.

41 - workarounds are good, but the test for whether pthreads are used
42 was not good. thisone should be better.
43 - check differently whether gcc generates cfi instructions itself.

46 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
47 destroyed and cleaned up automatically (e.g. async { schedule }).
48 - implement a JIT compiler for part of the thread switch code,
49 which gives a 50% speed improvement on threaded perls, and
50 about 4% on non-thraeded perls (so threaded perls now finally
51 reach about half the speed of non-threaded perls).
52 - slightly modernise Coro::Intro, add section about rouse functions.
53 - avoid DEFSV and ERRSV, giving another 10% improvement
54 in thread switching.
55 - Coro::State->is_destroyed is now called is_zombie.
56 - implement a Coro->safe_cancel method that might fail, but
57 cancels in a "safer" way if it succeeds.
58 - add preliminary support for DEBUGGING perls.
59 - get rid of two hash-accesses when initialising a new Coro - this
60 speeds up coro creation by almost a factor of two.
61 - croak when a coro that is being cancelled tries to block
62 (e.g. while executing a guard block), instead of crashing or
63 deadlocking.
64 - use a more robust and also faster method to identify Coro::State
65 objects - speeds up everything a bit.
66 - implement Coro->cancel in XS for a 20% speed improvement, and to
67 be able to implement mutual cancellation.
68 - speed up context switches by a percent or two by more efficiently
69 allocating context stack entries.
70 - implement Coro->join and Coro->on_destroy in XS for a speedup and
71 a reduction in memory use.
72 - cancelling a coro while it itself is cancelling another coro is
73 now supported and working, instead of triggering an assertion.
7 - be a bit more crash-resistant when calling (buggy) on_destroy 74 - be a bit more crash-resistant when calling (buggy) on_destroy
8 callbacks (bets effort). 75 callbacks (best effort).
76 - move on_destroy into the slf_frame, to allow extension slf
77 functions to have destructors.
78 - get rid if coro refcounting - simply crash in other interpreter
79 threads by nulling the pointers on clone.
80 - simplify warn/die hook handling when loading Coro - the convoluted
81 logic seems to be no longer neccessary.
82 - use libecb instead of our own home-grown gcc hacks.
83 - document alternatives to Coro::LWP. Please use them :)
84 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
85 sigaltstack. Really. wine suffers from it, erlang suffers from it,
86 and it's known since at least 2006.

11 - apparently mingw doesn't provide a working gettimeofday, try to 89 - apparently mingw doesn't provide a working gettimeofday, try to
12 work around that by relying on Time::HiRes (indirectly brought to 90 work around that by relying on Time::HiRes (indirectly brought to
13 my attention by Max Maischein). 91 my attention by Max Maischein).
