Since my last e-mail, I have been bombarded with numerous e-mail messages
    saying among other things that I contradicted myself in e-mail, class and
    the web site (you are right).  Many of you gave a good argument for my
    changing the order of the queue for an arrival.  You also made a good point
    in saying my first answer was the opposite of the last one and that I was
    "punishing" those of you who started early.
    
    I never meant to make a contradiction in ordering and will promise to be
    more careful in the future.  Those people who "yelled" at me and made such
    good arguments win!  As much as I hate to resend my previous e-mail, I feel
    that I have to.
    
    Here is the result:
    
    ready <--  A,B (a running)
    
    C arrives
    
    ready <-- B,A,C
    
    The argument that convinced me to change my mind was that an internal event
    gets processed first and that means that the running job would move prior
    to the arrival getting processed:
    
    The algorithm is:
    
    1.  run -> ready
    2.  process internal event
    3.  process external event
    4.  ready -> run
    
    Again, I do apologize.
