 * Make sure HttpSessionListener's sessionDestroyed(), and 
 * HttpSessionBindingListener's valueUnbound() methods are called when
 * session expires.
 *
 * Implementation note: According to SRV.7.5 ("Session Timeouts"), "the session
 * invalidation will not take effect util all servlets using that session have
 * exited the service method." This means that for this unit test, the
 * servlet that creates the session and the HttpSessionListener that waits for
 * the session expiration event are implemented as separate classes.
