21# DESCRIPTION:
22# 'zpool wait' works when a replacing disk is detached before the replacement
23# completes.
24#
25# STRATEGY:
26# 1. Attach a disk to pool to form two-way mirror.
27# 2. Modify tunable so that resilver won't complete while test is running.
28# 3. Start a replacement of the new disk.
29# 4. Start a process that waits for the replace.
30# 5. Wait a few seconds and then check that the wait process is actually
31#    waiting.
32# 6. Cancel the replacement by detaching the replacing disk.
33# 7. Check that the wait process returns reasonably promptly.
