9 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
10 destroyed and cleaned up automatically (e.g. async { schedule }).
11 - implement a JIT compiler for part of the thread switch code,
12 which gives a 50% speed improvement on threaded perls, and
13 about 4% on non-thraeded perls (so threaded perls now finally
14 reach about half the speed of non-threaded perls).
15 - avoid DEFSV and ERRSV, giving another 10% improvement
16 in thread switching.
17 - Coro::State->is_destroyed is now called is_zombie.
18 - implement a Coro->safe_cancel method that might fail, but
19 cancels in a "safer" way if it succeeds.
20 - get rid of two hash-accesses when initialising a new Coro - this
21 speeds up coro creation by almost a factor of two.
22 - croak when a coro that is being cancelled tries to block
23 (e.g. while executing a guard block), instead of crashing or
24 deadlocking.
25 - use a more robust and also faster method to identify Coro::State
26 objects - speeds up everything a bit.
27 - implement Coro->cancel in XS for a 20% speed improvement, and to
28 be able to implement mutual cancellation.
29 - speed up context switches by a percent or two by more efficiently
30 allocating context stack entries.
31 - implement Coro->join and Coro->on_destroy in XS for a speedup and
32 a reduction in memory use.
33 - cancelling a coro while it itself is cancelling another coro is
34 now supported and working, instead of triggering an assertion.
35 - be a bit more crash-resistant when calling (buggy) on_destroy
36 callbacks (best effort).
37 - move on_destroy into the slf_frame, to allow extension slf
38 functions to have destructors.
39 - get rid if coro refcounting - simply crash in other interpreter
40 threads by nulling the pointers on clone.
41 - simplify warn/die hook handling when loading Coro - the convoluted
42 logic seems to be no longer neccessary.
43 - use libecb instead of our own home-grown gcc hacks.
44 - document alternatives to Coro::LWP. Please use them :)

47 - apparently mingw doesn't provide a working gettimeofday, try to
48 work around that by relying on Time::HiRes (indirectly brought to
49 my attention by Max Maischein).
50 - fix some portability issues when Time::HiRes was used.

525.371 Mon Feb 21 14:36:08 CET 2011
53 - backport to windows process emulation code again.

555.37 Sat Feb 19 07:49:44 CET 2011
56 - add a big "Coro thread life cycle" section to "man Coro".
57 - try a tentative workaround against the breakage that 5.13 has
58 introduced without depreciation period. sigh.
59 - no longer use Time::HiRes if gettimeofday is available, which
60 saves quite a lot of memory.
