So my current todo list is:

• Change RT PULL
• Change DL PULL
• Add migrate_disable() tracer; exactly like preempt/irqoff, except measuring task-runtime instead of cpu-time.
• Add a mode that measures actual interference.
• Add a traceevent to detect preemption in migrate_disable().

And then I suppose I should twist Daniel's arm to update his model to include these scenarios and numbers.

Challenge accepted :-)
