The problem is that in gtk_main_iteration, when the event is GDK_DELETE or
GDK_DESTROY, it always does a gtk_widget_destroy after the call to
gtk_widget_event. 

I'm not sure what's the best way to handle this. Adding a boolean return 
value to the delete and destroy signal handlers makes sense, but could 
lead to problems if there is more than handler on the signal.
