I was following the steps at http://docs.python.org/library/profile.html
to try to profile a pygtk program, but it wasn't working -- I was
getting no output at all from either cProfile or profile.
The problem turned out to be that I was exiting by calling sys.exit(0),
because that's what most pygtk programs I'd seen were doing. Changing
that to gtk.main_quit() made profiling work (but it took a long time to
track that down).
Apparently the same thing happens in pyqt if you call sys.exit(0).

I'm note sure if this is a library bug, doc bug, external library issue or what, anyone got any true idea?

Profiling only works on functions that actually return; maybe we could
add something about this fact in the documentation
