			 * If we don't delay, we may loose data, but if we do delay, 
			 * there may not be data and the exit event never gets sent.

			 * before the exit event gets sent.  So the strategy here is
			 * to setup a timer event that will send the exit event after
			 * an arbitrary, but brief, time.
			 *
			 * This is probably paranoid, for the less paraniod, we could 
			 * check to see for Last Words, and only delay if there are any.
