Correct, basically a client once in a while revalidates everything in
the cache. If nothing changed in a volume between two validations it
remembers the volume version vector (VVV). Then when we reconnect we
first check the VVV to see if any of these volumes are still unchanged.

If they are, we clearly don't have to further check any of the files
until something is updated, at that point the server will break our
'volume callback' and we fall back on checking the individual files.
