Yes but: there's the obvious question of "how many C-g are
necessary", as well as making sure this doesn't misfire just because the
user hits C-g several times for some other reason.

IOW, to do this, we'd need to make sure that Emacs was busy font-locking
this one buffer during all this time, or something like that.

Also, I get the impression that we'd want this kind of behavior for more
than just font-lock.
