That's not unexpected at least, and matches my own (limited) experience
here. My gut feeling is that Py2.6 added a lot of "new in Py3.0" overhead,
but without all the optimisations that went into Py3.x since then. At least
some of that came back later with Py2.7.
Would be nice to (eventually) see Py2. run in speed.python.org in
order to get a better idea of the relative performance.
