Thanks for your efforts, but I think this is a wrong direction, that
will eventually get us into the same problem we have with unexec: the
need to know and depend on intimate details of relocations, memory
allocation, etc.  On top of that, adding Lisp objects will now require
writing its dumper back-end, so this will be a constant maintenance
burden of the kind that only a few of us can bear.

Making the initial load of preloaded Lisp files (most probably, a
single large file) fast enough to allow us to dump the dumping phase
altogether is a much more perspective direction.
