    The Native Client module executed in this page creates a thread that
    estimates pi (&pi;) using the Monte Carlo method.  The thread randomly puts
    1,000,000,000 points inside a square that shares two sides with a quarter
    circle (a quadrant).  Because the area of the quadrant is r&#178;&pi;/4 and
    the area of the square is r&#178;, dividing the number of points inside the
    quadrant by the number of points inside the square gives us an estimate of
    &pi;/4.  The textbox under the square shows the current estimate of &pi;.
