Rather than using get_properties and __wakeup for serialization the code now uses Serializable::serialize() and Serializable::unserialize(). The get_properties handler is switched to a get_debug_info handler. Thus get_gc will now return only the normal properties and not do any modifications, thus fixing the leak. This also avoids a $num property from being publicly visible after the object was dumped or serialized, so that's an extra plus.
