There have been quite a lot of (justified) complaints about the slowness
of C Mode's redisplay.  These wouldn't be helped by rewriting
font-lock.el as font-lock.c.  They might be helped by rewriting parts of
CC Mode in C.  This has already been suggested (by Eli), but hasn't been
explored in any great detail, as yet.
