No.  For one because using the same file descriptors as the one used
to set the hind actually makes it usable - finding the block device
does not.  And second as told about half a dozend time for this scheme
to actually work on a regular file the file system actually needs the
arbiter, as it can work on top of multiple block devices, consumes
streams, might export streams even if the underlying devices don't and
so on.
