It works!  Thanks for finding the problem and solving it!


BTW, what do you think about

      ;; Cancel timer for repeated invocations.
      (when (and (not repeat) (timerp jit-lock-stealth-repeat-timer))
        (cancel-timer jit-lock-stealth-repeat-timer))

and

        (if repeat
            (let ((cell (memq jit-lock-stealth-repeat-timer timer-idle-list)))
              (timer-set-idle-time
               jit-lock-stealth-repeat-timer (current-idle-time))
              (timer-inc-time jit-lock-stealth-repeat-timer delay)
              (timer-activate-when-idle jit-lock-stealth-repeat-timer t cell))

We currently allocate a new timer for every chunk we fontify stealthily
and for every buffer in `jit-lock-stealth-buffers'.  Is it worth the
trouble?
