According to POSIX priority value returned from pthread_getschedparam()
shall be the value specified by the most recent pthread_setschedparam(),
pthread_setschedprio(), or pthread_create() call affecting the target
thread. Read this as though a temporary lower priority due to the
sporadic server policy shall not be visible through
pthread_getschedparam(). Thus, use rtems_task_set_priority() to get the
current priority of the threads.
Use a priority ceiling mutex to prevent sporadic server priority
adjustments.
