I tried hand coding stuff at the pure Python level to see how close I
could come to David's results. I performed the operations in chunks
(larger chunks than he did so that Python overhead didn't kill me) For
the second case he presents (2*a+3*b), I managed to get a 70% speedup.
While not negligible, it's a far cry from the 180% speedup I saw with
David's code for the same result. So while doing things at the Python
level would certainly be easier, the payoff isn't likely to be nearly as
