Already in the works :)

As part of the common standard library and test suite that we agreed
on at the PyCon language summit last week, we're going to include a
common benchmark suite that all Python implementations can share. This
is still some months off, though, so there'll be plenty of time to
bikeshed^Wrationally discuss which benchmarks should go in there.
