Code review makes me think that if the timer fires at the same time as stop() is called, it would be possible for the clearing of events from the loop to happen before the event is put into the loop, leading to the sort of crashes we've seen with timers firing and access exceptions. I can't reproduce those to know if this fixes them, and I'm not even sure I'm not being dense thinking this patch fixes a real issue.
