"zfs send tank/usr/home/kevin at 2009-03-15-16:51:21|zfs receive
backup/kevin" hangs system and i have to power off the machine.when the
system up,i find file error in snapshot
tank/usr/home/kevin at 2009-03-15-16:51:21.when i destroy
tank/usr/home/kevin at 2009-03-15-16:51:21,then reboot system, i find more
errors.
