  21   Executes an infinite loop.

  23   Forces the CPU to execute an infinite loop. A debugger may be used to skip
  24   past the loop and the code that follows the loop must execute properly. This
  25   implies that the infinite loop must not cause the code that follow it to be
  26   optimized away.
