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.

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.
