I don't know, because I don't know enough about real-time scheduling.
What I envisioned is something fairly simple that would be easy to
implement. This probably means no sophisticated negotiation of
priorities or guarantees of access to the CPU. We'd need some sort
of basic protection to keep a process from eating up so much of
the CPU that you can never get on to the machine to kill it, though.
