This is btrfs with kernel 3.19. (.0-trunk from Debian), on a single volume
(on top of LVM but that should not matter).
I do this, on a freshly-booted system:
# mount /foo
# cd foo
# rsync -aPHAX . /bar
[ after an hour or so ]
^C
# cd ..
# fuser -m /foo
# ps ax | grep [ /]rsync
# umount /foo
This is 3.19, scanning an otherwise-idle filesystem on otherwise-idle disks,
mounted with noatime and nodatasum.

Hello,
how do I move a (read-only) snapshot?
Simply creating another read-only snap from the first one and then deleting
the source works, except that it destroy's the snapshot's identity -- which
means that it can't be used as a parent for btrfs receive any more. :-(
