I posted the results to have at least a single data point, as a "things
don't appear to be wildly different" reassurance. Agreed, that the
confidence interval is probably big enough to drive a bus through, and that
any claims of "faster" or "slower" are completely unjustified
statistically*.

I'm just scripting my test runner to switch directories to do the a/b
testing that you were suggesting earlier; perhaps I'll have some numbers to
post in a couple of hours.

* Except of course, if I had phrased it as the true fact that my two test
runs with Python 2.6 completed more quickly than my test runs with Python
3.2, which, perhaps, is what I should have done.
