We do not modify the mainline cgroup system, so it is the same
system whether you use it for Linux-VServer or KVM, which in
turn means, if it is broken in one of the upstream kernels
(and it looks like it has some issues in certain kernel versions)
it will be broken for Linux-VServer (and KVM) as well.
