I am sorry, I didn't get to your previous email. But this is quite
simply. You just echo those pids to a different cgroup. E.g. the root
one at the top of the mounted hierarchy. There are also wrappers to
execute a task into a specific cgroup in libcgroup package and I am
pretty sure systemd has its own mechanisms to achieve the same.
