        - (libcoro) fix misaligned stack points for setjmp and assembly
          methods, which can cause crashes on x86/x86_64 with a sufficiently
          aggressive compiler.
        - new function: Coro::Debug::new_tcp_server.
	- move ->throw into the Coro class because it only works on coro objects.

4.803 Mon Nov  3 17:16:12 CET 2008
	- (libcoro) use a global asm statement to become independent of gcc
          otpimisations for CORO_ASM (thanks to pippijn for the idea).
        - try to workaround yet another broken bsd, this time dragonfly.

4.802 Thu Oct 30 10:56:12 CET 2008
        - support -fno-omit-frame-pointer on x86 with the assembly method.
	- tune 01_unblock.t tests a bit.

4.801 Wed Oct 22 18:33:37 CEST 2008
	- improve readline speed for very long "lines".
	- backport to 5.8.8.

4.8  Thu Oct  2 13:34:40 CEST 2008
	- new function Coro::AIO::aio_wait.
        - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
        - greatly speed up and reduce memory usage of Coro::AIO requests.
        - implement some other µ-optimisations.

4.749 Mon Sep 29 14:40:12 CEST 2008
	- port to slow and broken pseudo-threaded perls. (courtesy pippijn).

4.748 Sat Sep 27 14:03:19 CEST 2008
	- implement, but do not document, PerlIO::cede(granularity).
	- Coro::Storable forgot to wrap Storable::pstore.
        - work around the multitude of leaks and memory corruption
          bugs in PerlIO::via by using our own C-level perliol. As a side
          effect, Coro::Storable is now much, much, much faster.

4.747 Tue Sep 23 01:59:41 CEST 2008
	- fix a per-cv memleak (one empty array was leaked per
          code reference).
        - avoid a crash in coro->call|rss when the coroutine was already
          destroyed (most noticably when using Coro::Debug::ps :)
        - also protect *Storable::FILE.
        - push up default storable granularity to 20ms.

4.746 Sun Sep 21 03:22:20 CEST 2008
        - be more insistent on locking Storable against reentrancy
          in Coro::Storable.
	- move swap_def?v and throw to Coro::State, as documented.

4.745 Thu Jul 24 00:14:38 CEST 2008
	- remove debugging code related to MgPV_nolen_const, also try to
          make it compile with perl 5.8.6 (yes, apple apparently loves
          outdated software). Reported by John S.

4.744 Tue Jul  8 22:06:35 CEST 2008
	- correctly provide default DIE/WARN handlers as documented.
	- also overwrite PL_vtbl_sigelem.svt_clear, even though current
          implementations inside perl work fine for us.

4.743 Mon Jun 16 00:21:57 CEST 2008
	- when using Coro::EV without running EV::loop it could
          result in busy-waiting for events, this has been fixed.
        - reduce codesize and improve performance by using EV_DEFAULT_UC.

4.742 Sat May 31 14:10:21 CEST 2008
	- implement a workaround for (some) perl <5.8.8 versions.
        - require EV 3.3+.

4.741 Fri May 30 23:33:09 CEST 2008
	- tell netbsd how utterly broken their imitation of an OS is
          and refuse to build by default if pthreads are in use.
        - switch to "s" method on all bsd's by default, as their ucontext
          stuff seems just too broken.
        - fix a bug in Coro::Select.

4.74 Thu May 29 20:05:31 CEST 2008
	- do not test Coro::LWP for lack of dependencies.
        - do not test Coro::Select for lack of working perls.

4.73 Thu May 29 2008
	- fix a bug in Coro::EV which would cause it to block despite
          there being runnable coroutines.
	- sprinkle "no warnings" freely over everything, also suppress
          warnings for some other modules.
        - fix typo in WSAEWOULDBLOCK.

4.72 Sun May 25 05:14:36 CEST 2008
	- tweak META.yaml a bit, unfortunately, there is no documented way
          to have optional dependencies with CPAN. doh :(
	- avoid running some tests on windows because they would fail due to
          perl bug (broken fork, broken pipes...).
        - work around perl on windows bugs where perl returns undocumented
          error codes for sysread, syswrite etc. by taking advantage
          of AnyEvent's workaround for that problem.
        - use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
          a common perl implementation bug on windows.
        - use unix domain sockets in testsuite to work around
          common perl implementation bugs on widows (they are emulated by
          tcp sockets on windows. ugh.)

4.71 Sat May 24 20:01:27 CEST 2008
	- fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
	- take advantage of async name resolution of AnyEvent::Util.
        - work around brutal inet_aton override in Coro::LWP.
        - take advantage of the readyhook in Coro::EV, for smoother
          scheduling.

4.7  Sun May 11 00:32:19 CEST 2008
	- completely reworked the Coro manpage.
	- added Coro::AnyEvent, generic event loop integration.
	- implement cancel, ready and kill commands in Coro::Debug.
        - document find_coro in Coro::Debug.
        - incompatible change: rename has_stack to has_cctx.
        - Coro::AIO and Coro::BDB no longer force event model detection,
          use AnyEvent::AIO and AnyEvent::BDB.

4.6  Sat Apr 26 10:05:14 CEST 2008
	- INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
          by the Coro module. It was a mistake to have it in the first place.
        - (experimental) support for activestate perl 5.10 (method "w").
        - (experimental) support for strawberry perl (method "a").
        - coro_sigelem_set did not return a value although it had to,
