The idea is that pragma priority should be restricted to "safe" priorities,
but then you need another pragma to access the full range. It was named
"Interrupt_Priority" to remind people that it gave access to interrupt
priorities, but it could have been named
"All_Priorities_Including_Interrupt_Priorities" ... Oh well....
