/*
 * The following 3 object classes are used to
 * simulate the kind of relationships seen in
 * qdev, which result in complex object
 * property destruction ordering.
 *
 * DummyDev has a 'bus' child to a DummyBus
 * DummyBus has a 'backend' child to a DummyBackend
 * DummyDev has a 'backend' link to DummyBackend
 *
 * When DummyDev is finalized, it unparents the
 * DummyBackend, which unparents the DummyDev
 * which deletes the 'backend' link from DummyDev
 * to DummyBackend. This illustrates that the
 * object_property_del_all() method needs to
 * cope with the list of properties being changed
 * while it iterates over them.
