Generally I don't approve of just adding an arbitrary delay to avoid a problem but in this case I'm going to let it slide. We may need to delay briefly after 'zpool destroy' returns to ensure the loopback devices are closed. If they aren't closed than losetup -d will not be able to destroy them. Unfortunately, there's no easy state the check so we'll have to make due with a simple delay.
