You'll find all sorts of fun bugs. For example, if you prelink a running
daemon, start-stop-daemon will generally refuse to stop it, as the
binary has changed. md5sum checking tools will puke all over the place.
Various programs will begin to crash (http://bugs.debian.org/prelink).
And I never managed to find a measurable speedup in anything important
(such as shell and perl).
