Oh, that's pretty sweet -- it means there's actually a way to reliably wait
for cleaner work to be done on all deleted snapshots before unmounting the FS.
I was wondering about that recently for some transient filesystems (which get
mounted, synced to, snapshot-created/removed, then unmounted). Now can just
loop with a few second sleeps until `btrfs sub list -d $PATH` comes up empty.
