Virtually all event loop implementations run until explicitly 
stopped.  PEAK's event loops are actually quite unusual in that they 
are capable of stopping automatically if there are no future events 
and no pending callbacks.

Compare with wx, Twisted, asyncore, the stdlib socket server classes, 
almost any GUI event loop, etc.
