----------
Sounds like enough reason in itself.  Sometimes we're talking about
LARGE amounts of data.  The ability to start in the middle when
doing something like starting nroff with a common macro set or
starting Lisp after it has loaded all the stuff it does as start
up, or starting a complex, extensible editor after it has already
extended itself, would be very useful (I gather GNU emacs does just
that).
