>From my previous reply:

   Not really.  After visiting a large file in C mode, I see some CPU
   time being used, probably to fontify the buffer, but it eventually
   stops after using only a very few seconds total time (four for alloc.c
   and maybe those four seconds were not even all used for C mode).

Well, that is four seconds total _CPU_ time, for visiting alloc.c
using `emacs -q' on a 1.7GHZ dual Xeon.  Emacs does not run _all_ of
the time, although a lot, takes a maximum of 3.something CPU and
finishes in about 3 minutes _clock_ time.  If your machine would be a
lot slower than mine and/or if your file is a lot larger than alloc.c,
it could last for much longer than 3 minutes (although your maximum
CPU usage is about the double of mine, which should halve the clock

So the questions are:

Do you see this in `emacs -q'?
Do you see it regardless of file size?
