Synchronizing on the session object may cause you all sorts of grief...or it may
not. It all depends on your container. The spec makes no guarantees about the
identity of the object returned by methods like PageContext.getSession or
HttpServletRequest.getSession. For example, here's a test JSP:

The sessions essentially just a sort of Map. Access to it may be

If you have 1 threads playing

I figured creating the session when the user showed up, destroying it
