Only on _some_OSes. What is the meddle to make this available for ANY OS?

A good solution has Solaris OS. It also knows as FSS (Fair Share
Scheduler) and projects/tasks.

Solaris also has possibility assign CPU cores as non-interruptable. In
addition to FSS. Thisfunctionality known approx. from Solaris 8 and
since 1993.

We have NO problem on REAL OS. There is the problem only for self-made
...... (censored) 'systems' which is pretend to be OS. In normal OS we
have scheduling table which has no real problem in the similar cases. Never.

Linux is [censored]. No more.
