This is something we may want to dig. from a checkpoint/restart POV, a 'container' acts a whole and you don't want tasks to be migrated from a container to another. They have to share the same container properties. it might be possible to solve that issue from user space or by making sure a set of cgroups are dedicated to a container. C.
