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.
