Cool - by passing in a socket, we can bypass qemu-nbd's insistence on 
TCP (still on my TODO list to get qemu-nbd to support TLS over Unix 
sockets, but socket activation does bypass that limitation), and avoid 
having to wait for the server to give us some indication that the socket 
is up (because it is already up).  I like it!
