It's not the fontification.  When I turn font-lock-mode off, it still
takes me 11 seconds (1.2 GHz Athlon) to display the page.  Whatever
takes the time isn't being cached, either, because it takes 11 seconds
_every_ time I display it.  Other pages are sluggish - to display Top
takes about 3/4 of a second.

In Emacs 21, Elisp's Index displays instantaneously enough.

Agreed.  But it's not the fontification.
