What is the correct way to make sure that DA's get their slices of the
pie when using WaitNextEvent?

My application, at one point, sits in a fairly tight loop waiting
for a mouse down.  It calls EventAvail.  It used, also, to call
SystemTask, per the documentation, to be sure that DA's got a chance
at the processor.  New docs say that if you call WaitNextEvent, you
shouldn't call SystemTask.  Ever?  Should I still be calling it in the
loop with EventAvail?  Or should I call something else (what)?  Or does
EventAvail do it automatically now?

Any enlightenment would be greatly appreciated.  Mail words of wisdom to:
