8TODO: testcancel 8 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
9TODO: aio 9 - Coro::Select did errornously dup the file descriptors
10TODO: Coro::Semaphore 10 and didn't work with all AnyEvent backends.
11TODO: trow disturbs cleanup path inside pp_slf? 11 - disassociate c contexts from coro objects - this is agruably more
12TODO: throw special-case in transfer? 12 correct, but mostly allows sharing of cctxs between coro and state
135.0 13 objects, for added memory savings and speed increases.
14 - bumped $Coro::POOL_RSS up to 32kb by default.
15 - no longer set the optype to OP_CUSTOM, as B::* understandably
16 doesn't like this very much (and we *are* a type of entersub).
17 - implement state cloning, just to prove that call/cc can be done.
18 - better 5.8.6 compatibility.

14 - NEW ARCHITECTURE: use the latest 4.x version if you experience 21 - NEW ARCHITECTURE: use the latest 4.x version if you experience
15 stability issues. 22 stability issues.
16 - bump API version to 7 - all dependents must be recompiled. 23 - bump API version to 7 - all dependents must be recompiled.
24 - removed timed_* functions - they were not being used anyways
25 and should be replaced by a more generic mechanism -
26 and were annoying to support anyways :)
27 - removed SemaphoreSet's waiter method - use sem method instead.
17 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 28 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
18 - async_pool did free a scalar value twice 29 - async_pool did free a scalar value twice

21 was waiting for a semaphore that was just becoming available 32 was waiting for a semaphore that was just becoming available
22 would cause a deadlock (semaphore would get into a state where 33 would cause a deadlock (semaphore would get into a state where
23 it was available but waiters were waiting(. 34 it was available but waiters were still blocked).
24 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 35 - calling throw on a coroutine that is waiting for a semaphore will
36 no longer make it acquire the semaphore (and thus leak a count).
25 - perl's process emulation is now not even theoretically supported 37 - perl's process emulation is now not even theoretically supported
26 anymore. 38 anymore.
39 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
40 conversion of callback-style to blocking-style.
41 - new methods $coro->schedule_to and ->cede_to, to specifically
42 schedule or cede to a specific coroutine.
43 - new function Coro::Semaphore::wait.
44 - use named constants in Coro::Channel (Richard Hundt).
27 - directly patch the entersub opcode calling SLF functions (cede, 45 - directly patch the entersub opcode calling SLF functions (cede,
28 transfer and so on). this does speed up context switching, but 46 transfer and so on). this does speed up context switching, but

44 - used new SLF interface to speed up Coro::AIO by roughly a factor of 59 - used new SLF interface to speed up Coro::AIO by roughly a factor of
45 four and reduce its memory usage considerably. 60 four and reduce its memory usage considerably.
61 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
62 for a nice speedup and vastly more correct behaviour. Also implement
63 a new method "sem" to get at the underlying semaphore object.
64 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
65 (in comparison) 20-40% speedup.
66 - used new SLF interface to reimplement Coro::Signal gaining
67 some unknown (because I was too lazy), but certain, speedup, and also
68 making signals reliable for the first time.
69 - used new SLF interface and other optimisations to speed up async_pool
70 by a factor of two. It also doesn't rely on perl's exception mechanism
71 to exit anymore. The overhead for terminating an async_pool, coro over
72 a normal async is now very small.
73 - sped up coroutine creation/destruction by 40%.
46 - forgot to include Coro/libcoro/README in the dist for all these years. 74 - forgot to include Coro/libcoro/README in the dist for all these years.

48 pthread_cond_wait isn't a cancellation point on freebsd). 76 pthread_cond_wait isn't a cancellation point on freebsd).
77 - use new rouse functions to speed up and simplify Coro::BDB.
78 - make "prefer perl native functions" work with threaded perls.
79 - condense Coro::Debug ps output, hint at v and w flags.
80 - (libcoro) lots of minor cleanups and portability improvements.
