I think this can go right after the generation of the event. That way it
can come "in order"...

Following the rest of the logic, event can be queued as it happens and
then "reused" in a few instances prior to event2 being generated. Then
at cleanup the most recent event and event2 get queued.

If you're OK with me moving that, then I can do so and push the two patches.
