Looks like a variant of gtk had this bug too.

Could we have put this code inside TimerBase::fired instead? Or does it not have an efficient way to check if the timer is non-repeating?

If stop() would do the trick on GLib too that would be neat.

Glib already had the implicit stop behavior. It needed the inverse fix: be sure to restart if you are a repeating timer. 

I do think we can/should do a shared implementation of isActive in TimerBase. Windows already has all the code we need; just need to migrate it. I hope to return and do that after I finish off callOnMainThread.
