>Description:
zfs destroy without -R options fails for any snapshot on _i386_ systems.
I have no this problem on my amd64 and sparc64 systems with same source code level.

>How-To-Repeat:
# zpool create tank `mdconfig -a -t swap -s 64m`
# zfs snapshot tank at snap
# zfs destroy -v tank at snap
will destroy tank at snap
will reclaim 0
# echo $?
1
# zfs destroy -rv tank at snap
will destroy tank at snap
will reclaim 0
# echo $?
1
# zfs destroy -Rv tank at snap
will destroy tank at snap
will reclaim 0
# echo $?
