Yeah, that's the problem the async code makes go away...

Hm...  didn't we add a mechanism to display messages on a timeout the
other year?  Or did we just talk about it?  I wanted something like

(with-timeout-message 2 "We're doing whatevs"
  (whatevs))

If the body form completes within 2 seconds, then nothing is displayed,
otherwise the message is displayed until the body form completes.

I can't find it now, so we probably just talked about it?
