I would like to see an example of how to do double buffered displays in
a FAST way.  I have seen and tried the method from the FISH example
(not to be confused with FISH disks), but it calls RethinkDisplay(), the
biggest CPU hog of all.  Unfortunately, my application cannot afford to
lose "several milliseconds" worth of time, especially when RethinkDisplay()
does a Forbid() and Permit() around all that CPU time.  The requirements
that I have are:  Page Flip must take almost zero time; Must be friendly to
intuition.

By friendly to intuition, I mean that I do not care if my screen can be 
pulled down or sent to the back (or front) - I do care that I can restore
the system so that Intuition will work when I exit (or do my own screen
to front and back gadgets).

Any help would be appreciated.
