It's running in the python shell (via emacs). So it never quits python
fully (emacs keeps the inferior python shell running as long as
needed).

It threw an exception in my code and dropped back to the python -i shell.

I could (if I was at the machine right now :-) but the exception is in
my code so it's probably not relevant. However the VisionEgg GL window
stays open. I tried myApp.screen.close() but that didn't seem to help.
