Postponed Emacs actions

[Lars Magne Ingebrigtsen <larsi@gnus.org>]

When one does things that usually takes a long time, you message to
tell the user that Emacs is doing whatever it's doing.

Filling paragraphs...
Filling paragraphs...done

However, in many cases the action doesn't take all that long, so you
just get a flutter of these messages, which is annoying.

Wouldn't it be neat if you could say

(maybe-message "Filling paragraphs..."
  (do-that-thing)
  ...)

and then that message would only be displayed if `do-that-thing' took
more than ¼ second.

Does this sound useful?
