Well, technically, but I regard it as stable in its behaviour.

It shouldn't be a problem, iwht only a few apps running the overhead is very small. If by "isn't perfectly tuned" you mean not running SCHED_FIFO or a patched kernel that its not that supprising, the context switch will be causing big problems. But, at worst it should just make xruns a bit more frequent, not go from none to some. IMHO any runtime xruns at all makes audio software unusable. - Steve
