Could you paste the results of running
http://www.osadl.org/projects-live-cd.0.html on the linux system(s) in
question?
Sounds like you have a specific set of requirements that do not fit
under a 'general application OS'.
RT is more than just how an OS handles threads -- syncronization
requires IPC communications.

That said, you still need OS support for it and, besides, I'm also talking about threads. You need low latency not only with the audio handling but also with capturing, filtering, and reoutputting the audio. Not to mention generating audio (via software instruments - ala VSTs).
