Does xemacs implement maillock itself? Emacs 20 doesn't, so emacs
20's maillock *would* be using liblockfile and so should be nfs safe.
The only problem that I've seen with emacs 20's movemail support of
maillock() (though I still don't feel qualified to be certain) is that
it appears to call maillock("full/path/to/spool", foo) rather than
maillock("username", foo).
Have you heard from James LewisMoss recently? I posted a propsal for
some immediate changes to the various emacsen which would move us
closer to supporting simultaneous install. I think Mark's OK with it,
but James hasn't said anything, and neither has anyone else...
My fear is everyone will only start screaming *after* I implement and
upload something :<

Well, I think we really need to get everything nfs safe -- silent
failures suck, and loss of mail sucks even more.

It might make sense to put movemail in emacsen-common. But that's
only good idea if xemacs, emacs19, and emacs20 expect the identical
semantics out of movemail...
