         - croak when a coro that is being cancelled tries to block
           (e.g. while executing a guard block), instead of crashing or
           deadlocking.
+        - use a more robust and also faster method to identify Coro::State
+          objects - speeds up everything a bit.
         - implement a Coro->safe_cancel method that might fail, but
           cancels in a "safer" way if it succeeds.
 	- implement Coro->cancel in XS for a 20% speed improvement, and to
           be able to implement mutual cancellation.
 	- speed up context switches by a percent or two by more efficiently
           allocating context stack entries.
+        - implement Coro->join and Coro->on_destroy in XS for a speedup and
+          a reduction in memory use.
         - cancelling a coro while it itself is cancelling another coro is
           now supported and working, instead of triggering an assertion.
 	- be a bit more crash-resistant when calling (buggy) on_destroy
           callbacks (best effort).
         - move on_destroy into the slf_frame, to allow extension slf
           functions to have destructors.
+        - get rid if coro refcounting - simply crash in other interpreter
+          threads by nulling the pointers on clone.
