It will have to re-examine the tail of the main list, as well as process
the current per-query list. I haven't really done any coding yet, but
I think this could be done pretty easily by appending the per-query list
to the main list (an easy pointer swing) and then proceeding as before.
Or it might be better to do it in two phases --- I'm not sure how hard
it is to keep track of whether it's safe to recycle fully-fired events.
Knowing that you are processing triggers generated by the current query
might be a useful leg up on that task.
Also, it's probably reasonable to assume that SET CONSTRAINTS doesn't
queue any new triggers of its own, meaning that in any given EndQuery
call only one of these tasks (rescan old triggers or scan new ones)
can be needed. That might or might not be worth exploiting.
