+	 * - $_class_abbreviations
+	 * - $NET_CFG (EE_Network_Config): The config is shared network wide so no need to reset.
+	 * - $REQ:  Still on the same request so no need to change.

+	 * - $SSN: Although ideally, the session should not be shared between site switches, we can't reset it because only
+	 * one Session can be active in a single request.  Resetting could resolve in "headers already sent" errors.
+	 * - $addons:  In multisite, the state of the addons is something controlled via hooks etc in a normal request.  So
+	 *             for now, we won't reset the addons because it could break calls to an add-ons class/methods in the
+	 *             switch or on the restore.
