  18  *   In 4.2 and below:
  19  *      session.auto_start and session objects are mutually exclusive.
  20  *
  21  * We need to load the classes before the session is started,
  22  * except that the session could be started automatically
  23  * via session.auto_start. So, we'll close the session,
  24  * then load the classes, and reopen the session which should
  25  * make everything happy.
  26  *
  27  * ** Note this means that for the 1.3.2 release, we should probably
  28  * recommend that people set session.auto_start=0 to avoid this altogether.
