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

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

27 - use even more efficient and more compatible condvars for
28 compatibility to AnyEvent 6.x :)
29 - more inconsequential ecb.h updates.

32 - change how Coro patches AnyEvent condvars for compatibility to
33 AnyEvent 6.x.
34 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
35 hasn't been included.

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

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

14 reach about half the speed of non-threaded perls). 54 reach about half the speed of non-threaded perls).
55 - slightly modernise Coro::Intro, add section about rouse functions.

17 - Coro::State->is_destroyed is now called is_zombie. 58 - Coro::State->is_destroyed is now called is_zombie.
18 - implement a Coro->safe_cancel method that might fail, but 59 - implement a Coro->safe_cancel method that might fail, but
19 cancels in a "safer" way if it succeeds. 60 cancels in a "safer" way if it succeeds.
61 - add preliminary support for DEBUGGING perls.

43 - use libecb instead of our own home-grown gcc hacks. 85 - use libecb instead of our own home-grown gcc hacks.
86 - document alternatives to Coro::LWP. Please use them :)
87 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
88 sigaltstack. Really. wine suffers from it, erlang suffers from it,
89 and it's known since at least 2006.
