This module doesn't really do anything. It's supposed to be used as a placeholder until you decided on a "real" CGI::Session interface to use. This would make sense if you had to set up a complicated database or other backend to store sessions. However, by default CGI::Session easily stores files in a "tmp" directory. Usually, zero configuration is required for this. As a CGI::Session user myself, I just don't see the need for this module.
