Does the following make any sense?
(defun rng-validate-while-idle-continue-p ()
;; input-pending-p and sit-for run timers that are
;; ripe. Binding timer-idle-list to nil prevents
;; this. If we don't do this, then any ripe timers
;; will get run, and we won't get any chance to
;; validate until Emacs becomes idle again or until
;; the other lower priority timers finish (which
;; can take a very long time in the case of
;; jit-lock).
(let ((timer-idle-list nil))
(and (not (input-pending-p))
;; Fake rng-validate-up-to-date-end so that the mode line
;; shows progress. Also use this to save point.
(let ((rng-validate-up-to-date-end (point)))
(goto-char rng-validate-display-point)
(when (not rng-validate-display-modified-p)
(restore-buffer-modified-p nil))
(force-mode-line-update)
(let ((continue (sit-for 0)))
(goto-char rng-validate-up-to-date-end)
continue)))))
