Note that Mako can use the Markupsafe library for faster operation. This will skew the result if one of your Pythons has Markupsafe installed and the other does not.
Perhaps the benchmark runner should launch its subtests in a controlled environment to avoid such issues? (shipping a copy of Markupsafe would not be very practical, because it has a C extension)
