With large numbers of queued vblank, the list iteration on every
interupt dominates processing time. If we reorder the list to be in
ascending event order, then not only is also likely to be in order for
notification queries (i.e. the notification will be near the start of
the list), we can also stop iterating when past the target event_id.
