That was a red herring. Neither did splitting the mirror and building a completely new zpool and using zfs send ... | zfs receive ... to transfer the data prevent the problem occurring. There's a PR about this: kern/156781 Only solution I've found to getting the snapshot dirs back is to reboot, but ZFS will crash on shutdown when this problem is occurring.
