What do I do when I want a certain lengthy process to be done in
the background, so the user can switch to another applicaition
if he wants, but I want to check for the existence of
MultiFinder before wasting the extra CPU time catching events
(so I know if he switched out) and calling WNE while in
the background?  As for now, I'll just have to do it all the
time.
