#
# DESCRIPTION:
# 'zpool wait' works when waiting for devices to complete initializing
#
# STRATEGY:
# 1. Create a pool.
# 2. Modify a tunable to make sure initializing is slow enough to observe.
# 3. Start initializing the vdev in the pool.
# 4. Start 'zpool wait'.
# 5. Monitor the waiting process to make sure it returns neither too soon nor
#    too late.
