It _appears_ to be a valid test-case. I can reproduce this with
2.5.64+combo and B2. I can also influence it to behave. (that doesn't
mean that the scheduler changes are bust... could be that the test-case is
doing something bad)

Q/indicator: do you ever see ksoftirqd _wanting_ to run? (set top SCHED_RR)
