> * Understand the relationship between cpu.shares and CFS quota.
> * Determine range of possible bias splits
> * Determine how to achieve bias, e.g., should 20:1 be 20480:1024 or ~1024:50
> * Rigorous testing of behavior with varying loads, particularly the combination of latency sensitive loads for high biased tasks (non-revokable), and cpu intensive loads for the low biased tasks (revokable).
> * Discover any performance edge cases?
