+        - croak when a coro that is being cancelled tries to block
+          (e.g. while executing a guard block), instead of crashing or
+          deadlocking.
+        - implement a Coro->safe_cancel method that might fail, but
+          cancels in a "safer" way if it succeeds.

+	- speed up context switches by a percent or two by more efficiently

+        - cancelling a coro while it itself is cancelling another coro is
+          now supported and working, instead of triggering an assertion.

-          callbacks (bets effort).
+          callbacks (best effort).
