Hi,
Some folks here may be interested in a recent discussion of pre-emption
in the 2.6 kernels and potential issues with it.
See:
http://kerneltrap.org/node/view/2702
This is very interesting. It says that preempt have no influence
on the worst-case latency. In other words, this means that
preempt in theory is useless regarding use of realtime audio.
