OK, here's the deal. IIRC, signal handlers properly deal with thread
stuff, but idle functions, i/o-watchers, and timeout functions do *not*.
They are not put into their own thread, at least, not as far as I can
tell, but they don't properly deal with threads from a gtk/gdk level,
either. Therefore, whenever dealing with one of the latter, make sure
to wrap yer gtk/gdk code in gtk.threads_{enter,leave}

Democracy is two wolves and a sheep voting on what to have for dinner.
Liberty is two wolves attempting to have a sheep for dinner and
finding a well-informed, well-armed sheep.
