OK

Consider users with always <= 2 windows per frame: If `display-buffer'
displays some temporary buffer in the other, reused window, shrinking it
to some few lines, calling `switch-to-buffer-other-window' in that
situation won't be of much fun.

When we get such a request you'll take care of it ;-)
