just as a side note, when I was doing performance latency testing (for 
industrial robotics applications) on real-time Linux kernels (RTAI, soft 
real-time preempt, and hard real-time preempt) I noticed that I got 
better latencies when when I loaded up the system with a LOT of 
processes and workload.  If you end up looking into the RT stuff, let me 
know off list and maybe I can send a link or six.
