1.5 What does clone_children do ?
---------------------------------
If the clone_children flag is enabled (1) in a cgroup, then all
cgroups created beneath will call the post_clone callbacks for each
subsystem of the newly created cgroup. Usually when this callback is
implemented for a subsystem, it copies the values of the parent
subsystem, this is the case for the cpuset.

What: namespace cgroup (ns_cgroup)
When: 2.6.38
Why: The ns_cgroup leads to some problems:
* cgroup creation is out-of-control
* cgroup name can conflict when pids are looping
* it is not possible to have a single process handling
a lot of namespaces without falling in a exponential creation time
* we may want to create a namespace without creating a cgroup
The ns_cgroup is replaced by a compatibility flag 'clone_children',
where a newly created cgroup will copy the parent cgroup values.
The userspace has to manually create a cgroup and add a task to
the 'tasks' file.
