> Say one use --slave_subsystems=cpuacct
> However, if he/she does not use cpuacct cgroup for isolation, all processes forked by the slave (e.g., tasks) will be part of the slave cgroup. This is not expected. ALso, more importantly, this will cause the slave to flap when restart because there are task processes in slave's cgroup.
> We should add a check during slave startup at least!
