520 Sorting the counter lists reduces the amount of work that
521 has to be done when a counter tick is processed, since the
522 next alarm to expire is always at the front of the list.
523 However, it makes adding an alarm to the list more expensive
524 since a search must be done for the correct place to put it.
525 Many alarms are used to implement timeouts, which seldom trigger,
526 so it is worthwhile optimizing this case. For this reason
