I implemented a very simple session module which mostly works --- it
worked well enough for the task I had at the time. It generates an
opaque session identifier which corresponds to the name of a file on
disk containing pickled session data.

As I look at it now, it isn't robust in the face of multiple clients
sharing the session id, but as I said it was written in about twenty
minutes for an internal app.

Are there any decent ones? I remember doing a brief search and not
finding anything I immediately liked.

I'd certainly be interested in tossing my code over the fence as the
seed for a more robust session manager.
