I agree absolutely with all the statements. However, I also think we should undertake an incremental approach, otherwise we end-up with nothing. For this round, we're discussing about how to improve CPU scheduling. This is only one of the essential bricks that are needed in order to support real-time applications and increase predictability of software. Of course, a comprehensive approach to the problem needs to consider other resources as well, like networking and disk transfers, as well as the IRQ subsystem architecture. Still, improving CPU scheduling is just a little step that is strongly needed, has a relevant impact on the problem, and it can be done without subverting the way scheduling and resource management is handled inside the kernel.
