35TODO: warnhook reports from wrong line number now, when arg is Math::GMP number.
36 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess
37 to report a full stacktrace, which should help find out
38 where the actual call is.
39 - "atomically" destroy data in slf_destroy, because it is
40 the right thing to do, just in case.
41 - disable ecb.h libm dependency, to compile on ancient systems
42 or under adverse conditions.

446.33 Mon Nov 18 11:26:27 CET 2013
45 - do not crash when freeing padlists with holes (in 5.18).
46 - tentative SVt_BIND 5.19 port/fix.
47
486.32 Tue Nov 5 15:35:35 CET 2013
49 - use a new algorithm to derive padlists for perl 5.18. The old
50 one could lead to 0-pointer accesses inside perl (reported
51 by Darin McBride).
52
536.31 Thu May 9 07:39:48 CEST 2013
54 - Coro::AIO requests would crash if the thread was ready'd
55 while the request was ongoing.
56
576.29 Wed May 8 02:55:18 CEST 2013
58 - when an on_destroy handler destructs the coro currently being
59 destructed a perl scalar could be accessed after being freed,
60 likely causing a crash.
61
626.28 Wed Mar 6 06:58:02 CET 2013
63 - clean remnants of existing __DIE__ and __WARN__ handlers so
64 they lose their magic and will not cause segfaults later
65 (testcase by Andrey Sagulin).
