I hadn't paid much attention to this before, but testing on large
*compilation* buffers showed it affects my builds too.

I'll apply any speed up patches submitted.  For whoever wishes to work
on this we appear to be font-locking the entire output buffer
repeatedly while error messages are being collected, then we have a
second phase I don't see in Emacs 19.34 where another pass is done to
parse the error messages.

M-x grep int *.[ch]

in the XEmacs 20.0 C source directory was the test case I used.
