  18  *      session.auto_start and session objects are mutually exclusive.
  19  *
  20  * We need to load the classes before the session is started,
  21  * except that the session could be started automatically
  22  * via session.auto_start. So, we'll close the session,
  23  * then load the classes, and reopen the session which should
  24  * make everything happy.
  25  *
  26  * ** Note this means that for the 1.3.2 release, we should probably
  27  * recommend that people set session.auto_start=0 to avoid this altogether.
