Need help resolving accidental (honest!) language pissing match

[Jeff Epler]

Here's my try, using numarray:
    import numarray, numarray.random_array, numarray.nd_image
    n = 1000000
    x = numarray.random_array.randint(-1, 2, (n,))
    x = numarray.add.accumulate(x)
    mean = numarray.nd_image.mean(x)
    st_dev = numarray.nd_image.standard_deviation(x)
    print mean, st_dev
This runs for about .6 seconds on a 2.4GHz PC running Linux.

I'm not sure whether the results are right, but at least the program
finishes quickly, and involves a random array, a running sum, and some
statistics.
