    Added some very minor comments and a simple benchmarking script.
    
    Using this script I saw a 13X regression in stdGen in recent revisions
    vs the 1.0.0.3 version, dropping to only 900K random ints/sec on my
    machine.  However, it was some kind of heisenbug because now it's gone
    away for unknown reasons.  Watch out for it in the future though.
