      Description

      It would be nice if we could have the nodemanager run at a different OS scheduling priority than the containers so that you can still communicate with the nodemanager if the containers out of control.

      On linux we could launch the nodemanager at a higher priority, but then all the containers it launches would also be at that higher priority, so we need a way for the container executor to launch them at a lower priority.

      I'm not sure how this applies to windows if at all.
