 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.
+        - process swicthing is much faster now.
+        - very minor optimisations and code/documentation cleanup.
+        - avoid problems due to compiler inlining.
+        - possibly better support for threads.
+        - removed timers from Coro::Timer -> use AnyEvent instead.
+        - replaced Coro::idle coroutine by (cleaner) idle handler.

         - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
