Al Viro likes Plan9 process-local namespaces.  He seems to be trying to
move Linux in that direction.  In the past year he has been hacking the
semantics of filesystems and mounting, probably with namespaces as an
eventual goal, and this is one of the things that has fallen out of the
implementation.

A more useful thing to fall out of the same hacking is loopback
mounting -- i.e. the same filesystem mounted multiple places.  In
Linux-land I guess we call it 'mount --bind'.
