Reproduced even with lxc-stop.

-----------------------------------------
cgroups are clean -- absolutely no vm-X folders under
/sys/fs/cgroup/*/lxc/
lxc.network.type is now 'veth' as I've moved off of using 'phys', but
the result is the same.
This happened after lxc-start / lxc-stop somewhere between 7k and 15k
times. Similar number as reported last time this happened, which really
suggests a leak of some sort.
I have the box in this state right now.
What other details could be helpful?
