In the past I'd thought a device namespace would mainly do something
like translate maj:min on host to maj:min in a namespace.  But after
seeing the demo twice, I agree with the need for an extra "active" vs
"inactive" state, with buffering in the "inactive" state.  That's
something we don't have in any other namespace and sets devicens apart.
