  Hmmmmm.  Interesting point.  I believe that automatic recovery upon
  system startup works slightly differently though.  It happens when the
  IFS driver is initialising.

  If the IFS hasn't fully initialised, then there won't be any files
  open to the actual physical device (because you need an IFS in order
  to have open files in the first place, even the swapper).  So you can
  lock it.

  And we know that CHKDSK *does* lock the drive that it is checking,
  because we know that we cannot check the boot or swapper partitions.
