Could this be a
possible solution to the in-process xrun issue?
http://www.onlamp.com/pub/a/onlamp/2002/11/07/linux_threads.html
there is no "in-process" xrun issue. the problem is for
"out-of-process" clients. the problem has nothing whatsoever to do
with the pthreads implementation, and everything to do with the kernel
scheduler and worst-case kernel scheduling latencies.
Would compiling the kernel with HERTZ > 100 (say, 500) help?
I imagine it would because the scheduler would run more often.
