        - Al Viro announcing per-process namespaces on lkml

this is probably not going to be helpful right now, but there
are patches for this in Linux in development which will almost
definitely be in the main kernel.  if you're feeling
adventurous, go to ftp://ftp.math.psu.edu/pub/viro and check out
the 'namespace' patches there.  they will give every single
process their own directory tree.
