So we'd have cases like this, assume we start with a full event

	thread A		thread B

	dequeue event
	aha, new connection
	accept()

	add kevent on new
	connection

At this point thread A doesn't have very many options when the kevent
add fails.  You cannot force this thread to read more events, since he
may not be in a state where he is easily able to do so.

There has to be some thread that is responsible for reading events. Perhaps a 
reasonable thing for a blocked thread that cannot process events to do is to 
yield to one that can?
