15 * From http://www.php.net/manual/en/language.oop.serialization.php:
16 * In case this isn't clear:
17 * In 4.2 and below:
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.
