  Nope, all in lisp.  Emacs/W3 still does do it, I just didn't remember the 
function name correctly.

(defun url-lazy-message (&rest args)
  "Just like `message', but is a no-op if called more than once a second.
Will not do anything if url-show-status is nil."
  (if (or (null url-show-status)
          (active-minibuffer-window)
          (= url-lazy-message-time
             (setq url-lazy-message-time (nth 1 (current-time)))))
      nil
    (apply 'message args)))
