Added a count of the number of users of this block device, and refuse to close
down the frontend until that number becomes 0.  There are no reasonable
semantics for hot-unplugging a block device beneath a mounted filesystem, and
this solution ensures that the guest is not crashed nor the filesystem corruptedby the actions of the administrator.
