I think the "lingering issue with device_del" is that my broken battery is 
causing my laptop to overheat...  So I'll fold patch 23 into the right spot and 
repost tomorrow.

Could use another set of eyes to walk through the reference counting stuff 
though.  It's a bit nastier than I would like it to be.  I really dislike the 
notion of having an object_unparent in the unplug path.
