Looks interesting.  I guess I should have qualified my answer
by saying something like "platform-specific code might allow for
other solutions". :-)  I'm pretty sure cancelable.py's solution
wouldn't work on Windows (but if I'm wrong, then of course:
"amongst our choices are separate process, non-blocking socket,
connection from another thread, and cancelable.py, and of course
an almost fanatical devotion to the Pope...")  ;-)
