One observation in the bug report is that atleast KeyboardInterrupt needs to get a chance to get through, making bare except clauses evil under almost any circumstance. Regards, Martin

That would explain why sometimes I have to hit ^C twice to kill the test suite.

There's a standard idiom for this:

try: ...code... except KeyboardInterrupt: raise except: ...handler...

That's easy enough to add to doctest (I looked and it seems obvious that this will work).
