> 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.
