No, it's really a simpler alternative to running a session server. The cgi
itself is responsible for writing the pickled sessions to the filesystem.
The implementation was kept deliberately simple and portable - it should
work under windows (although this hasn't been tested). This does mean
that there is no provision for sharing the sessions between servers
(the file access is *not* NFS safe, because the techniques used would
upset windows, and there are better alternatives anyway).

As Dave said, you can run a single session server, and have multiple
front ends hit this server (since the server protocol is TCP).

Currently the session server is not persistent - if you restart it, you
lose all the currently open sessions. Future work will add some sort of
presistent store (maybe libdb).
