That's why the XEmacs portable dumper is better than the current Emacs

Right, a portable dumper would be nice to have.
Tho I don't know enough of the details to know what are the downsides
(e.g. does it require relocation?  If so that means the file can't just
be mmap'd read-only and shared between processes, right?).

If I'm reading the XEmacs Internals documentation properly, pdump *may* require relocation, but not if the offset at which the dumpfile is loaded happens to match the offset at which it's loaded. That's about as good as you can ask for.
