How do we clear a bogus zpool?

[Sean Bruno]

I've managed to create a situation where I have a completely bogus zpool
showing up on my system.  There seems to be no way to wipe this out?

# zpool import           
   pool: zroot
     id: 854190767471294680
  state: UNAVAIL
 status: One or more devices are missing from the system.
 action: The pool cannot be imported. Attach the missing
        devices and try again.
   see: http://illumos.org/msg/ZFS-8000-3C
 config:

        zroot                     UNAVAIL  insufficient replicas
          raidz1-0                UNAVAIL  insufficient replicas
            17925463268209287656  UNAVAIL  cannot open
            11020448220822113890  UNAVAIL  corrupted data
            10143858893287711942  UNAVAIL  corrupted data
            7542790596970715955   UNAVAIL  corrupted data
            10811885036534933813  UNAVAIL  corrupted data
            13343774937261906429  UNAVAIL  corrupted data

# zpool destroy -f zroot
cannot open 'zroot': no such pool
# zpool clear -F zroot
cannot open 'zroot': no such pool
