epoll_wait() is a valid sleeping reason for real-time tasks because it uses PI-aware locking, but the rtapp sleep monitor documentation only discusses clock_nanosleep() and futexes. Document it. ABORT_SLEEP represents a task restoring TASK_RUNNING before entering the scheduler. Since the task does not actually block, it becomes runnable again without a wakeup sequence unsafe for real-time. Document this behavior.
