21# DESCRIPTION:
22# 'zpool wait' works when waiting for devices to finish being trimmed
23#
24# STRATEGY:
25# 1. Create a pool.
26# 2. Start trimming the vdev in the pool, making sure the rate is slow enough
27#    that the trim can be observed.
28# 3. Start 'zpool wait'.
29# 4. Monitor the waiting process to make sure it returns neither too soon nor
30#    too late.
