Confirming bug based on the report of this in #chatzilla. While we could just
set an upper limit to the number of events processed each step (which is what I
did for the reporter to solve the problem), this would not be preferred, as the
eventsPerStep variable should NEVER be Infinity in the first place. If anyone
has a clue as to what may have caused this, that would be most helpful.

Is that what happened? eventsPerStep was Infinity?

(not all of us were in #chatzilla ;) )

Yes, that is what happened. I asked the reporter to eval the parameters used for
the event queue, because they are the things that tend to cause slowdowns.

Attachment: Patch

Patch to check for the time difference to be bigger than 0 (having it be 0
causes the increment newValue to go to Infinity)

Not totally sure this will fix the bug, but it can't hurt.
