Right now there is no way to define a real-time queue in libdispatch, but would this kind of extension be theoreticaly possible? What would be the way to do that? Any comment on the overall idea?

Hi, I think it would be possible to add realtime support to libdispatch, although you would also need changes to pthread_workqueue(3) libc functions. It sounds like you are using the Mach function thread_policy_set(), which is not portable and also not very general-purpose. Have you tried using pthread_setschedparam(3) with the SCHED_FIFO scheduling class, and would this approach be acceptable for JACK? Regards, - Mark
