I almost forgot about this one...
After reading the whole series, I can't understand the above explanation
any longer. The parent can't be from different namespace, either we have
another sub-thread, or we reparent the child to /sbin/init which should
be from the same namespace.
If we are /sbin/init, we kill all tasks from the same namespace before
Could you clarify?
