> We have been trying to roll out CGROUP enforcement and right now are running
> into a number of race conditions in the supervisor. When using CGROUPS the
> timing of some operations are different and are exposing issues that we would
> not see without this.
> In order to make progress with testing/deploying CGROUP and RAS we are going
> to try and refactor the supervisor to have a simpler threading model, but
> likely with more threads. We will base the code off of the java code
> currently in master, and may replace that in the 2.0 release, but plan on
> having it be a part of 1.x too, if it truly is more stable.
> I will try to keep this JIRA up to date with what we are doing and the
> architecture to keep the community informed. We need to move quickly to meet
> some of our company goals but will not just shove this in. We welcome any
> feedback on the design and code before it goes into the community.
