If you are interested you may check the example I provided in my
recent emacs.devel thread. *Completions* is somehow closed before
comint-dynamic-list-completions is finished
(comint-dynamic-list-completions doesn't exit immediately upon showing
*Completions*).

Hm, nice idea. But isn't display-buffer-function called from
display-buffer (infinite recursion)? I'll check it when I get to my
Emacs box.
