The claim of statelessness should not be taken too literally. When one
of our disks got trashed (@*#% Xylogics!), we did the "obvious" thing -
we took the server down, created the filesystem afresh, restored all of
the backup tapes, and then let the clients continue where they left off
before the crash. Talk about some confused clients...

"Stateless" only means that the state is kept on disk rather than RAM.
