    Description

      Currently the destroyer would attempt to kill processes in a cgroup tree in parallel.

      However it could result in two threads trying to freeze and thaw a parent and a child cgroup concurrently and repeatedly and it's possible that neither would make progress so it will lead to the containerizer not able to destroy the container within a timeout, after which point the agent/containerizer just gave up, leaving the (partially) frozen container holding system resources (e.g., ports).
