If I may...

Not so fast (pun intended)! A Media OS needs plenty of throughput. It
might be prudent to have variable scheduling quantas for R2, and some
flags to let the kernel know some thread is in charge of media related
I/O. This almost becomes a non-issue on multicore machines, where an
entire (pool of) core(s) could conceivably be dedicated to "zippy",
small-quantum threads, and higher latency, I/O heavy threads could be
bound (affined) to a separate (pool of) core(s).


Not to raise expectations too much, but now I'm really wondering what
kind of magic scheduler you're planning to create for us. ;)
