The problem is that if you have a bunch of smart-refresh windows on the
screen, and do much window manipulation, they each get chopped up into a
whole bunch of super-small bitmaps and updating becomes pure agony. Simple
refresh is slightly (slightly! If you use a single Text() call for each
line of text you output, it's damn fast) slower for the simple case, but
its behaviour doesn't degrade nearly as badly.
