#
# DESCRIPTION:
# 'zpool wait' works when waiting for resilvering to complete.
#
# STRATEGY:
# 1. Attach a device to the pool so that resilvering starts.
# 2. Start 'zpool wait'.
# 3. Monitor the waiting process to make sure it returns neither too soon nor
#    too late.
# 4. Repeat 1-3, except using the '-w' flag with 'zpool attach' instead of using
#    'zpool wait'.
