I don't think thats it.  I think its a chicken and egg situation.  I think the
problem is that tasks can't be assigned to cgroups until their created, and in
that time a sock can be created.  Its a natural race.  If you create a socket
before you assign it to a cgroup, that socket retains a classid of zero.  I'm
going to try modify the patch to update sockets owned by tasks when the cgroup
is assigned.
