[~jieyu] comments welcome.
> Breaking out sub-process tracking from the slave.
> -------------------------------------------------
>
> Key: MESOS-1421
> URL: https://issues.apache.org/jira/browse/MESOS-1421
> Project: Mesos
> Issue Type: Improvement
> Reporter: Timothy St. Clair
>
> I had recently treaded through the cgroups and tracking code to enable
> systemd support and I was struck by the amount of work the slave has to do.
> In other grid systems, the slave typically forks a worker whose job is child
> process tracking, cleanup, etc.
> In the future, if the full extent of namespaces are leveraged, and the init
> process goes down, then the children go down. This would alleviate that
> potential problem, but it may be an architectural change.
> Not to mention, it's a clean separation of concerns.
> e.g.
> slave<>worker<>executor
> in condor-speak:
> startd<>starter<> job
