 *   In case this isn't clear:
 *   In 4.2 and below:
 *      session.auto_start and session objects are mutually exclusive.
 *
 * We need to load the classes before the session is started,
 * except that the session could be started automatically
 * via session.auto_start. So, we'll close the session,
 * then load the classes, and reopen the session which should
 * make everything happy.
 *
 * ** Note this means that for the 1.3.2 release, we should probably
 * recommend that people set session.auto_start=0 to avoid this altogether.
