But that just will not happen with current unpatched kernels. High IO will
starve even RT processes. You will need to patch the kernel with low-latency
or preempt patches. You might even need to change the scheduler (yet
another patch...).

2.4.x vanilla is a PoS in certain areas. The VM is one. The latency is
another. With dumb xmms, it cannot help but cause skips. Use something
better, with huge output buffers, and you will not have so much trouble. Or
patch the kernel.
