I did a crude implementation of session variables for my OSCON tutorial
which can be found here: http://www.joeconway.com/tut_oscon_2004.pdf
See the slides with myfunc_setvar(), myfunc_getvar(), and myfunc_rmvar().
I have a slightly improved version that I'm using on a production system
with good results. You can get the tarball here:

There was another implementation of session variables based on shared
memory floating around the lists somewhere. You might try searching the
archives for that also.
HTH,
