NOTE: deterministic hard-rt is not about speed, it's about determinism. While Ingo's work is great at reducing latency, it cannot guarantee response times regardless of the load, kernel configuration, and driver set.

Purpose of the Project
The purpose of this effort is to to further reduce interrupt latency and to dramatically reduce task preemption latency in the 2.6 kernel series. Our broad objective is to achieve preemption latency bounded by the worst case IRQ disable.
Does this qualify? It's "bounded" yes? The bounding would qualify as true real-time, and the reduction of latency beyond that bound would just be a happy responsiveness bonus. Am I right? If not, please show err.
