Indeed.  Mark, havn't you noticed that KDE, Gnome and Mozilla are
high on the list of projects that complain about startup time?

And no, caching and prelinking don't help here since we're dealing
with weak symbols.  Those can't be prelinked and wind up on the
conflict list (which uses yet more runtime memory, btw) which gets
resolved after the rest of prelinking is complete.
