Austin Eng a526167e33 Make child objects ref the device and add a mechanism to break cycles 
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.
