Wow, Python much faster than MatLab

OT, but why are you slicing array1 and array2? All that does is create new array
objects pointing to the same data.

Pretty much. Making the array types builtin rather than from a third party
module doesn't really change anything. However, if type inferencing tools like
psyco are taught about numpy arrays like they are already taught about ints,
then one could do make it avoid temporaries.
