True for a one-shot routine that has run and has no next time: the dispatcher disables a one-shot
once it fires, so "Disabled" here means "done", not "broken". A one-shot still waiting for its
time is not spent, whatever it has run before (a manual run keeps the schedule); a one-shot that
was disabled before ever running is just disabled; a recurring routine is never spent.
