http://docs.sun.com/app/docs/doc/806-4125/6jd7pe6cm?a=view Call it "soft" real-time; neither device interrupts nor (AFAIK) disk I/O reorderings inherit process priority. (I recall for example that Harris VOS could do something like both of those, but of course it wasn't Unix, although in a limited way it could pretend to be.) So note in particular the headings under that URL "Synchronous I/O Calls" and "Interrupt Servicing". One may be able to do other interesting things as well, such as designate some of the (virtual) CPUs as not handling interrupts, leaving them totally free for other work. With multiple (virtual) CPUs, one could bind processes to individual CPUs or to sets of them, or do other interesting things to ensure resources were dedicated to particular process(es). AFAIK, no support for the SCHED_SPORADIC scheduling policy for pthreads.
