Priorities can be tricky. You need to understand whether the Systems
Programming and/or Real Time annexes are in effect, and what the
policies are. Read the compiler documentation. You need to know how
many CPUs you have. On some operating systems, you might need to run in
supervisor mode in order to get strict real-time priorities.
