- * Should the body of the search loops in _Thread_queue_Enqueue_priority

- * two "nodes" on the chain being searched. Otherwise, only one node
- * is examined per iteration.
- *
- * If TRUE, then the loops are unrolled.
- * If FALSE, then the loops are not unrolled.
- *
- * The primary factor in making this decision is the cost of disabling
- * and enabling interrupts (_ISR_Flash) versus the cost of rest of the
- * body of the loop. On some CPUs, the flash is more expensive than
- * one iteration of the loop body. In this case, it might be desirable
- * to unroll the loop. It is important to note that on some CPUs, this
- * code is the longest interrupt disable period in RTEMS. So it is
- * necessary to strike a balance when setting this parameter.
