I've wondered about this for over a year now, but haven't brought it up because of not making it to the BF events. Now I can't stand it anymore and must ask.

It's not a true realtime interrupt. Some events may be recognized immediately (e.g. a new "mailbox" message, and some may be recognized on a 100 millisecond background scan (e.g. a "click" event).
