Can the current fileserver code cope with two copies of itself
(belonging to different cells) running on a single machine?  If you
compiled two copies of OpenAFS with different --prefix= flasgs, would
there be any problems remaining (other than fighting over the same UDP

I've always been a bit troubled by "ThisCell"... it is a nice
simplifying assumption to insist that each server machine belongs to
exactly once cell, but lifting that restriction has advantages.  How
deeply into the AFS code is this assumption ingrained?  Do on-disk
volumes "know" what cell they belong to (is it written in a file
somewhere inside /viceX/?)
