This is being worked on and looked at now through the use of some sort of daemon in the running container but is not currently possible. More over, cgroups in the kernel does not currently support joining an active cgroup, and may never support it, so it would have to be done through the mediation of some sort of daemon in the running container and communicating with the host. There's been discussion on the -devel list over the optimal way to do it and there are some patches running around but AFAICT nothing has really been committed or committed to at this time.
