hm, this shouldnt be the case. Can you see this with -v14?

for containers it's exactly the right behavior: group scheduling is
really a 'super' container concept that allows the allocation of CPU
time regardless of how a group uses it. The only additional control we
might want is to allocate different amount of CPU time to different
groups. (i.e. a concept vaguely similar to "nice levels", but at the
group level - using a different and saner API than nice levels.) Nice
levels are really only meaningful at the lowest level.
for 'friendly users' it's perhaps not what we want - but those do not
need to isolate themselves from each other anyway.
