Looks good. I think --force should be more brutal (i.e., assume that we have
already politely requested the disconnection, if that's what we really
wanted).

Apart from that, we should remember that if we need to use --force then it
probably indicates a problem in the frontend driver. If you can repro a
situation that requires --force then we should investigate that (and work
out a patch for blkfront).

 Thanks,
 Keir
