This is not a regression. Ubuntu is configuring the kernel with
CONFIG_FAIR_USER_SCHED, which changes the behaviour.  You can utilize
the feature more effectivly with uevent scripts (to which I have
linked in an earlier comment)

CONFIG_FAIR_CGROUP_SCHED will allow finer control of group scheduling,
with the option not to use by not making any groups and putting
everything in just one group.

that mean something other than this bug is not a bug?]
