That's what I'm hoping for.

Cross platform testing is already automated with TravisCI (Linux
covering major Python 2 and 3 versions and PyPy) and buildbot
(which also covers Windows, Mac and Jython).

There are however gaps in the functional test coverage - contributions
are most welcome. Some of these *may* well expose bits of Python 2
only code which will need minor revision to work on Python 3.
