Hmm, true. In my application I have a 500ms QTimer which gives control
to the python VM briefly so exceptions are handled.

Though that makes me wonder if there is a way for PyQt to call qFatal
on Python exceptions if the user doesn't handle exceptions any other
way, so by default exceptions would terminate the application?
