FYI, this is the default on a single CPU system.

->key problem is pfGetPWinWSWindow don't work in APP process when multiprocess
->case. man page say it works, but it don't.
It does work but the window has to have been opened first for you
to be able to get anything back. The window will be opened in the
draw process which isn't even running until after the first call to
pfFrame(). Since we don't propagate requests from one app frame until
you have called pfFrame(), you have to call pfFrame() after the request
to open the window. Even so, since it is an asynchronous request,
if you call pfGetPWinWSWindow() right away you still might get back
0x0 and might have to loop waiting for the result. An example of
how to more resonably structure such code is in pguide/libpf/C/complex.c
where each frame we check to see if the window is initialized and then
once get back an indication that it is go and do all of the other
X window hook-up stuff.
Hope this helps,
src.
