#
# DESCRIPTION:
# 'zpool wait' works when a replacing disks.
#
# STRATEGY:
# 1. Attach a disk to pool to form two-way mirror.
# 2. Start a replacement of the new disk.
# 3. Start 'zpool wait'.
# 4. Monitor the waiting process to make sure it returns neither too soon nor
#    too late.
# 5. Repeat 2-4, except using the '-w' flag with 'zpool replace' instead of
#    using 'zpool wait'.
