 Revision history for Perl extension Coro.
 
+TODO: check wether stack-sharing is still effective
+TODO: more effective stack sharing by having one "default stack" for "simple" coroutines?
+TODO: verify exception frame changes and force stack copies?
+
+	- reimplement a new stack sharing algorithm.
+        - make stack sharing mandatory (it no longer uses a heuristic).
+        - Coro::Event could cause livelocks if it was used but
+          Event watchers were used directly.
+        - Coro::Event should be cleaner and more efficient now.
+        - minor incompatibility: subclassing is supported directly now
+          without going through a _coro_state member.
+        - state/coro switching is much faster now.
+        - very minor optimisations and code/documentation cleanup.
+        - avoid problems due to compiler inlining.
+        - removed timers from Coro::Timer -> use AnyEvent instead.
+        - replaced Coro::idle coroutine by (cleaner) idle handler.
+        - updated to newest libcoro.
+
+2.5  Tue Nov  7 12:22:33 CET 2006
+        - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
+          use AnyEvent, moved them to Coro/.
+	- added Coro::LWP which contains all the uglyness required to
+          make LWP non-blocking.
+	- should work with perl 5.9.x now (Andreas König made me do it).
+        - fixed another bug in Coro::Select when the timeout was undef.
+        - reuse PL_start_env for all coros, saves some memory per coroutine.
+        - manage PL_top_env differently, hopefully to avoid panic: top_env.
+        - timeout argument was not properly used in Coro::Socket.
+        - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
+        - emulate undocumented(!) functionality of IO::Socket required
+          by LWP(!!).
+        - updated eg/lwp to work with newer lwp's.
+        - remove "FATAL: uncaught exception" prefix. Coroutines that die
+          kill the whole process, just as exceptions in the main "coroutine"
+          did already.
+
+2.1  Wed Nov  1 23:01:13 CET 2006
+        - fix a long-standing bug in Coro::Select where select with
+          zero timeout would instead change the current default filehandle.
+	- use a simpler and hopefully more robust way to clone padlists
+          (uses less memory and a perl function instead of our own).
+        - coro can now create a stack guard area on many architectures.
+        - Coro::AIO properly reexports additional functions from IO::AIO.
+	- updated libcoro with a workaround for OS X,
+          pach and testing by Michael Schwern.
+
+2.0  Tue Oct 24 05:47:17 CEST 2006
+	- support additional aio requests in Coro::AIO.
+
+1.9  (never properly released due to a glitch)
+
+1.8  Thu Feb  2 00:59:06 CET 2006
+	- applied suggested patch by SAMV to avoid problems during stupid
+          mark & sweep gc run.
+        - applied patch by Scott Walters for 5.9.3 compatibility.
+
+1.7  Tue Dec 27 01:41:58 CET 2005
+	- added Coro::AIO, a thin wrapper around IO::AIO.
+	- improved Makefile.PL explanations.
+
+1.6  Mon Dec 12 21:30:05 CET 2005
+	- additionally save PM_curpm might fix as-of-yet
+          unseen problems with regex matches being attributed to the
+          wrong package.
+        - add t/10_bugs.t, which currently checks against imho broken
+          perls that use 0.26MB of stack space per Perl_magic_get
+          invocation (newer linuxes) as opposed to the 0.0002MB perl
+          normally uses.
+        - make stacksize configurable for the ultimate debian experience.
+
+1.51 Mon Dec 12 18:48:36 CET 2005
+	- remove debugging warn() accidentally left in Coro::Select.
+
+1.5  Tue Nov 29 13:32:44 CET 2005
+	- use Coro::Event inside Coro::Select to avoid spurious deadlocks.
+        - fix Coro::Select 'select'.
+        - strict'ify some modules.
 	- libcoro errornously restored the SIGUSR2 handler to SIGUSR1.
+        - use XSLoader in selected modules.
+        - remove some 5.6 compatibility cruft.
 
 1.4  Tue Sep  6 00:11:05 CEST 2005
 	- libcoro did not take into account the trampoline on amd64,
