Not so -- if we allow (but ignore) the object to update, code can
be written as if it DTRT.

(defun redisplay-now (&optional object)
  "Force immediate display update of all windows.
If optional arg object is a frame, update display of that frame only.
If optional arg object is a window, update display of that window only.
If object is a buffer or buffer name, update display of all windows
displaying that buffer."
  ;; There is currently no way to update individual windows, so
  ;; update everything.
  (let ((redisplay-dont-pause t))
    (sit-for 0)))

Of course, in this form, it redisplays way too much if you specify a
window or frame object, but in most cases, nobody will be able to notice!
