Well, I got delayed a bit.  Below is my patch for speeding up frame
creation by sharing fontsets between frames.  It works fine on my
system; frame creation feels almost instantaneous again.  I think
applying it should not mess things up too badly.

(An Arch changeset for this patch is available as
lorentey@elte.hu--2004/emacs--fontset-cache--0--patch-3.)
