Thanks very much for the explanations.

Unfortunately this hook is not available in Emacs 21.

This is probably the way to go. I tried this and it works very well.
(For Emacs 21 I put the contents of `jit-lock-force-redisplay' into an
anonymous function passed to `run-with-timer'.)

That would be nice, yes. For now I am relieved that this could be
solved from within AUCTeX as well.
Thank you very much for your valuable help.
