In reply to my own question, if the motion_notify_event handler calls
event.window.get_pointer() to get the x,y position of the mouse and the
buttons state then the events keep occurring. If, as I was doing, you
just print a debug message and don't bother grabbing that information
the event only happens once.
Odd.
