10 - use fd -1 in mmap.
11 - cast I32 to int in error message printf.
12 - warn about broken so-called "hardened" kernels.

146.08 Fri Apr 13 12:05:47 CEST 2012
15 - be more aggressive about exiting like perl does - formerly,
16 exiting from the non-main thread would not execute END blocks.
17
186.07 Fri Nov 11 21:21:48 CET 2011
19 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
20 - update ecb.h.

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

33 - blush, condvar values would not be propagated from send to recv anymore
34 (reported by Chip Salzenberg).
35 - use exponential increase for the readline buffer length in
36 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
37
386.04 Wed Aug 3 17:15:45 CEST 2011
39 - use even more efficient and more compatible condvars for
40 compatibility to AnyEvent 6.x :)
41 - more inconsequential ecb.h updates.
42
436.03 Wed Aug 3 11:41:30 CEST 2011
44 - change how Coro patches AnyEvent condvars for compatibility to
45 AnyEvent 6.x.
46 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
47 hasn't been included.

50 - "improve portability to Gentoo" - gentoo manages to put perl variables
51 in memory areas that are farther than 2gb apart, which the jit couldn't
52 handle and barfed. now it's just a bit slower on gentoo and similar
53 systems.
54
556.01 Sun Jul 3 12:31:14 CEST 2011
56 - workarounds are good, but the test for whether pthreads are used
57 was not good. thisone should be better.
58 - check differently whether gcc generates cfi instructions itself.

14 reach about half the speed of non-threaded perls). 66 reach about half the speed of non-threaded perls).
67 - slightly modernise Coro::Intro, add section about rouse functions.

17 - Coro::State->is_destroyed is now called is_zombie. 70 - Coro::State->is_destroyed is now called is_zombie.
18 - implement a Coro->safe_cancel method that might fail, but 71 - implement a Coro->safe_cancel method that might fail, but
19 cancels in a "safer" way if it succeeds. 72 cancels in a "safer" way if it succeeds.
73 - add preliminary support for DEBUGGING perls.

46 sigaltstack. 100 sigaltstack. Really. wine suffers from it, erlang suffers from it,

49 - apparently mingw doesn't provide a working gettimeofday, try to 104 - apparently mingw doesn't provide a working gettimeofday, try to
50 work around that by relying on Time::HiRes (indirectly brought to 105 work around that by relying on Time::HiRes (indirectly brought to
