Ah, you're right that other packages won't use add-function, so they'll
stomp on our advice!

So it sounds like you'd indeed be happy with an input-event-hook.

Then maybe the (new in 24.4) pre-redisplay-function could be used
for that. Something like
(add-function :before pre-redisplay-function
(lambda (wins)
(if (or (eq t wins)
(memq <mybuffer> (mapcar #'window-buffer wins)))
<take-foo-down>)))
Of course, this will require some care, since a redisplay happens
probably right after you've set things up (i.e. before you start
waiting for user input), and you don't want *that* redisplay to trigger
the <take-foo-down>.
