Update child objects to ref the device. This allows them to outlive the device, making the implementation more robust such that it is OK to drop the device before other objects. Dropping the last external reference to the device is currently an implicit device.destroy(). This destruction breaks possible ref cycles where the device refs internal objects which have a back ref to the device.
