Done.  I also updated the lispref manual to clarify this issue.

You mean something like this?

  /* Bind inhibit-quit to t so that C-g gets read in
     rather than quitting back to the minibuffer.  */
  int count  = SPECPDL_INDEX ();
  specbind (Qinhibit_quit, Qt);

  timer_start_idle ();            
  sit_for (Vminibuffer_message_timeout, 0, 2);
  timer_stop_idle ();

  /* Clear the echo area.  */
  message2 (0, 0, 0);

I don't really see why it's important (it's currently just a two
second pause in which idle timers don't run), and I don't know the
code well enough to know if it will break anything horribly.
