It also doesn't help the problem where emacs needs to read the user's mind to
figure out if the user wanted to cancel font-lock or whatever other process was
running. Experience with predecessors to font-lock that were interrupted by C-g
(so, admittedly quite old) suggest that emacs will guess wrong often enough
that users will (did) find the colorizing not worth the headache. We might be
able to do better now, but it isn't obvious to me how, and C-g handling is
already pretty quirky when you consider all of the platforms, IIRC.
