Well said! This is obviously a new area and, aside from the obvious
problems, we may still get interesting interactions with some of the
more exotic things regularly found in our environments (e.g. Lustre,
InfiniBand, etc.). It's going to be "fun" working it out...

And of course, we're now hitting problems on the cluster I'm testing this
out on. Sometimes, attempting to delete the cgroup causes the process to
spin the CPU and some kernel threads. Lovely :)
Anyone with insight into this, please feel free to jump in!
