Mmm... It was actually a question, but I must have hit "," instead of the "?" mark... By the way, I think we are talking about different kind of realtime. With "Hard realtime" i mean that the application can preempt the kerenl itself. When the application can preempt the OS ( like when you sets nicelevel to -20 ) I talk about it as "Soft realtime". I don't think you would like to run a multimedia app in hard realtime because it would probably violate the stability of the entire system. Othervise I agree with you that a "Soft realtime" API would be a cool thing for user space apps to use. :) Perhaps it allready exists? Perhaps the question should be: "What are the realtime abilitys of the Hurd kernel/Hurd OS today, and in a possible future?" // Liss
