No known implementations.  I looked into it back in 2005 and was
unable to come up with a viable solution at the time.

The only way I could see it happening offhand is the cmd module and
overriding it to avoid raw_input, and use stdin/stdout instead.  And
also monkey-patching stdin and stdout to be opaquely non-blocking and
stackless compatible.
