Does anyone know the purpose of this node, i.e. what consumes it?
docs/misc/xenstore-paths.markdown doesn't mention it, neither do any of
xen/include/public/io/*.h AFAICS.

The backend needing to know the name (as opposed to domid) of the
frontend domain seems rather unusual to me.

Perhaps we should just nuke this key?
