I've had much more luck the other way around.  GTK calls go into the  
main thread and I start new threads for other computations, etc.  The  
other threads never touch GTK, they tell the main thread what to do.   
I started back in Gtk 1.something with pygtk 0.6.x and I just was  
never able to get my threads to cooperate when they all tried to do  
GTK call, so I avoided that.
