In the case where (load-average) is too high, the idle timer may not
get control back until up to 30 seconds later:

    ;; Wait a little if load is too high.
    (when (and jit-lock-stealth-load
               (> (car (load-average)) jit-lock-stealth-load))
      ;; In case sit-for runs any timers,
      ;; give them the expected current buffer.
      (with-current-buffer outer-buffer
        (sit-for (or jit-lock-stealth-time 30))))))))))))))
