This is really good advice thank you.
I've been messing with this today and I've found that a priority as low
as 5 seems to be enough for even an extreme case
of very small feeder buffers, short feeder sleep times, with itunes
playing, Finder copying a couple of large files, and me dragging and
resizing project builder's windows. amazing my feeder didn't seem to
drop a frame. So it seems that even a low priority rt thread is pretty
much guaranteed to get it's time at the moment. It'll be interesting to
see how it goes when several music apps are playing together.
