--- Comment #1 from Todd Fiala <todd.fiala at gmail.com> ---
This one is somewhat perplexing.  

On the multiprocessing test runner, where I'm usually seeing this on OS X, I've
put try/except blocks around the subprocess calls, thinking it was happening
there and uncaught.  Still happens with that.

Then I put a try/except around the main abstract test runner call, thinking for
sure it would at least get caught there.  Nope.  Still happened without the
exception block getting caught.

I'll put a try/catch around the main routine.  If that doesn't catch it, I
might need to look into the multiprocess Queue or multiprocess Manager to see
if one of those can choke in some cases.
