Yes, my normal way of doing this was to emit gobject signals from the
worker thread, but I never realized that the signal handlers are
called from the same thread as the emitted the signal. I naively
assumed the signals were passed to the gtk.main() loop.

Thanks for informing me about this. Now I have to go apply that
gobject.idle_add() trick in a few places.
