Thanks for the reminder to rejoin that list.

It’s pretty obvious from the above run what’s going on from the output. A 
similarly named zpool (same prefix; suffixed with a 2) is being matched by 
grep, even though the test sets up one with a suffix in the preceding steps.

It’s probably and issue with timing and the bhyve implementation for amd64 vs 
i386, or something else.
