The idea, roughly speaking, is to limit the number of outstanding work
items in the queue (basically, if there's a notification occurring
before the previous one can be handled, there is no need to queue up
another work item for it).
That's easier said than done, though, because of the way the work item
queue-up is hooked up into the ACPICA code.
