[Lxc-users] dangling cgroups after lxc-execute with ns_cgroup

Hi,

I updated to lxc-0.8.0-rc2 and after that I observe dangling cgroups
(/cgroup/PID) in the filesystem after lxc-execute terminates.

I am using ns_cgroup.

Looks like a process is spawned in a new namespace but lxc-fails to remove
the cgroup directory.

After a long time these dangling cgroups collide with new PIDs and
lxc-execute fails with "File exists".

Apparently caused due to commit -
http://lxc.git.sourceforge.net/git/gitweb.cgi?p=lxc/lxc;a=commit;h=69182a318c3ba35f56a88891cabad25d9f7985b6

This problem does not happen if I go to an earlier revision.

Thanks,
Arun
