Dtwm.  Or any window manager that doesn't really support the EWMH, for
that matter.  I would simply suggest:

(defun ediff-make-control-frame-utility-window nil
  "If non-nil, make the Ediff control frame a ``utility window''.

Most X window managers will then order the control frame above all other
windows as long as it remains visible.")

I strongly object to Emacs trying to document behavior that is actually
defined by individual window managers, because we will receive
complaints from users about Emacs not behaving as expected, when in fact
it is their window manager that behaves differently.
