	I don't quite understand what the problem is, beyond the fact that the
threads are de-coupled. Ultimately (surely) - depending on how long the
processing code is that handles the event in the main-thread, many
events can pile up being pushed from the other thread.

	If you want to block the other thread while waiting for the main-loop
to process the request; then I assume you want a different sort of
locking primitive. Surely making all notifications block the notifier is
not a good model ;-)

	Ultimately surely, in any threaded world - notifications should contain
either no state, or sufficient state for the listener to act; since
subsequent fetches of state from the object may result in odd effects
(?).

	Confuseldly,

		Michael.
