I've thought about these issues and was wondering if it would be
better to pre-create the data base connection, and maybe even the
cursor in a completely separate process. Then have modpython
communicate to it via a simple local socket. I assume there still is
overhead when create a local socket -- but it might be less then a
data base connection.

It might be tempting to want to layer a whole new light protocol on
top of that when sending data to the socket -- but maybe sending a
simple python pickle would be enough.

As a side, is there any difference in communicating via a socket and a
unix pipe?
