You could try writing a small testbed which turns off regular font-lock
and allows to _manually_ trigger refontification (and contextual
refontification) according to what jit-lock and font-lock would do in
case of a buffer change.  Then you could step through these routines
with edebug without being hit by intercepting timers.

It is a good idea. I could extend my testbed like that.

However if a user discovers the problem it would be good to have a debugger that writes a log somewhere that a user can send with a bug report.
