While I've got little to add the discussion of the innards, this
occurred to me also. In fact, I've been trying it -- I figured that
a "redump Emacs after load .emacs" would be a fairly attractive option,
especially if it was automated.

Anyway, at the moment, I can't get it to work. Calling this:

(dump-emacs-portable "~/scratch/test.pdmp")

after loading my .emacs works (early versions crashed, so something's
been fixed there). However, trying to use this:

./src/emacs -q --dump-file ~/scratch/test.pdmp 
emacs: could not load dump file "/home/phillord/scratch/test.pdmp": not a dump 
file
