One more point that I have to remember to mention once I write its wiki
page: The attachment handling code is NFS safe, because it never
modifies existing files. So there won't be problems with using director
to distribute users to different servers and still all servers accessing
the common attachment storage.

Another thing I just remembered: The code currently uses 0600 / 0700
permissions for everything. I guess it should take the permissions
from /attachments directory and preserve them for all the subdirs/files.
