I'm not sure I understand what you mean by "suspending" (it normally means
to stop working by relinquising the CPU, like when you hit C-z or when
you close a laptop).

That still does not explain why "fontifying".  Was it just a strange gut
feeling or was there some indication that it was related ?

It only changes the maximum file size past which fontification is
turned off.  And by default in Emacs-21, jit-lock is turned on in which
case font-lock-maximum-size is ignored anyway.

What is the major-mode used for this file ?
Can you try the M-: (setq debug-on-error t) RET and then use C-g ?

Nah, the output of "top" is just useless.
