The above patches are included in https://launchpad.net/ubuntu/+source/systemd/215-6ubuntu2, but they still don't work quite right: They seem to work well through VT logins and ssh, but not through lightdm. There's some race condition somewhere which removes PIDs from the session cgroup controllers again and moves them back to either or /user.slice.
