You mean doing the same as in calendar?  Things like

                  (lambda (buf)
                    (split-window nil height (eq type 'horizontally))
                    (other-window 1)
                    (switch-to-buffer buf)))

look suspicious because `switch-to-buffer' without FORCE-SAME-WINDOW set
can now make the behavior differently wrt Emacs 23.

No.  I mean the same as above.  More precisely

    (let ((choices-window (get-buffer-window ispell-choices-buffer)))
      ...
        ;; Overlay *Choices* window when it isn't showing
        (ispell-overlay-window (max line ispell-choices-win-default-height)))
      (switch-to-buffer ispell-choices-buffer)
      (goto-char (point-min)))))

does strange things when `switch-to-buffer' does _not_ use the window
selected by `ispell-overlay-window'.  You can, for example, get an extra
window showing the initial buffer.

We have to rewrite ispell's window handling from scratch.
