Never mind - I figured out how to force it to occur in a test, and 
have fixed the bug.  next_event_time() is now tested to not return 
zero or negative numbers when time advances, and the underlying 
problem (not depending on the rule that removed the already-occurring 
events from the schedule) has been fixed in SVN.  Thanks for the bug report!
