Do not notify the main thread more than needed. Basically, we suppress the notification when an event is added or deleted and: - The event has no fd, or there is no change in whether we are reading/writing on the event's fd. - The event has no timeout, or adding the event did not make the earliest timeout become earlier. This should be a big efficiency win in applications with multiple threads and lots of timeouts. svn:r1439
