The sleep (unsigned long) param to WaitNextEvent is the time (in ticks) to
relinquish the processor if no events are pending.

The mouse (RgnHandle) param is used to allow non-critical mouse movements.
It specifies a region within which you don't care if the mouse moves around,
like the cursor doesn't change, etc. If the mouse moves outside this region,
the application will get a "moused moved" event, which is a null event with
new mouse co-ordinates.

I haven't actually used all this yet, I'm just quoting the Release Note of
8-6-87.
