Or, to put things in a more negative way...

What is the point of flushing a secondary buffer into the primary buffer 
if we're not going to flush to the screen?  Why not just wait to do it?

Certainly the GTK clients do such a flush - although they don't call 
gdk_flush, the flush is implicit since it takes place shortly 
afterwards.  The only time this makes a difference is when animation is 
done - and the animation will call gdk_flush.
