Can you elaborate on this please?  I'm not directly familiar with 
cgroups, I'd greatly appreciate a quick-and-dirty example of using BIO 
cgroup to limit I/O bandwidth.

Limiting bandwidth definitely would ameliorate the problem for me; I 
already use pv's bw-limiting feature to make btrfs send | btrfs receive 
tolerable.
