As I didn't see any disc activity, I thought it was done.

I just tried it again, it does seem to work the way you mentioned.

Thanks.

Just a quick question: would 'btrfs filesystem sync /path' help speed
that up ?

Like for example if a sys-admin sees that he's running out of space and
needs
to remove some old snapshots immediately.

Or when an automated backup first removes old snapshots to create room
for a new backup just before starting that backup.
