Subject: 25.1.50; Wishlist: There should be a way to postpone messages

When doing stuff that takes an unknown amount of time, it would be handy
to have a form like

(with-delayed-message "Contacting server..."
  (contact-the-server))

If the body form completes within reasonable time (defined by
`delayed-message-timeout', say 1 second), no message is displayed.  If
more time than that passes, the message is displayed until the form
exits.  This has to happen no matter what Emacs is doing -- blocking on
DNS resolution, or running Emacs Lisp code.

When the body exits, the message (if it has been displayed) is cleared
(and any previous message shown in the echo area is restored).

Would with-timeout fit the bill?

`with-timeout' aborts processing of the form, which is not what we
want...

Is with-temp-message closer to what you have in mind ?

`with-temp-message' always displays the message, so it's not what I
want.
