i'm well aware of Steve's benchmarking efforts, but i dont think he's
finished with it and i'll let him present the results once he wants to
announce them. I asked about the effects of the "2-d" patch in isolation
and i'm not sure the numbers show that individual patch in action.

in any case, you are preaching to the choir, i wrote the first
rt-overload code and it's been in -rt forever so it's not like you need
to sell me the concept ;-) But upstream quality requirements are
different from -rt and we need to examine all aspects of scheduling, not
just latency. In any case, i'll wait for the rest of Steve's numbers.
