- *
- * Let N be the maximum priority of this scheduler instance. The SuperCore
- * priority zero is system reserved (PRIORITY_PSEUDO_ISR). There are only
- * N - 1 POSIX API priority levels since a thread at SuperCore priority N would
- * never run because of the idle threads. This is necessary because GNAT maps
- * the lowest Ada task priority to the lowest thread priority. The lowest
- * priority Ada task should get to run, so there is a fundamental conflict with
- * having N priorities.
