Or...  is something else going on here?

I put in an explicit `while' here, because

DEFUN ("while", Fwhile, Swhile, 1, UNEVALLED, 0,
[...]
  while (!NILP (eval_sub (test)))
    {
      maybe_quit ();
      prog_ignore (body);
    }

So we're calling maybe_quit here:

(with-delayed-message 0.5 "Yes"
  (dotimes (i 1000000)
    (let ((j 0))
      (while (< j 1000)
	(setq j (1+ j))))))

Still, it's not triggered.  Hm.
