    :  I was more thinking of redundancy like this for performance.  Say I

    :  processors running the same job simultaneously, I can check which   
    :  result is correct (by a majority vote)   
    :   
    :  This uses the theory that as the clock speed of the part moves out of

    :  further out of the working region, the further it goes down.

   Can you fillin a blank please? What's the application?
