> Currently, the Pid targeted by the cgroups isolator is moved into the cgroup before the subsystem runs to apply any type-specific cgroup configuration. We should reverse the order of this so that the PID is only moved once the cgroup is fully configured by the subsystem.
> The specific use case that affected us was where a PID was assigned to a {{net_cls}} cgroup before that cgroup had the class ID set. This caused a separate system to become confused.
