Right, so why not simply making the timers buffer-local, too?  I've
tried that

--8<---------------cut here---------------start------------->8---
(defun th-jit-lock-defer-fontification ()
  (interactive)
  (make-local-variable 'jit-lock-stealth-timer)
  (make-local-variable 'jit-lock-stealth-repeat-timer)
  (make-local-variable 'jit-lock-context-timer)
  (make-local-variable 'jit-lock-defer-timer)
  (set (make-local-variable 'jit-lock-defer-time) 0.1)
  (font-lock-mode -1)
  (font-lock-mode 1))
--8<---------------cut here---------------end--------------->8---

and it seems to work exactly as expected. :-)

Thanks,
Tassilo
