While I still don't understand where the slowdown actually comes from
(e.g. why do 1559 calls to put-text-property take 0.01s with -Q -D but then
take 5.46s with a loaded .emacs?  Also more than half the elasped time is
unaccounted for in the profile of the pathological case), we can always try
and move some of Info-fontify-node into font-lock-keywords where jit-lock
should help us stay nice and responsive.
