Take care since this would toast the disks for any other recovery 
attempt.  The data may very well be available, especially if the file 
is small (since zfs typically writes 128k at a time).  Recovery is 
easiest if the pool was a single disk or mirrored rather than raidzN.

There are only something like 20 transaction groups available to go 
back to and this might span only a few seconds to a 100 seconds worth 
of time.  If the file was destroyed long before the problem was 
noticed, then this approach won't work.
