Hi Thomas,

Thanks for the reminder. I'm not comfortable pushing this while we don't
notice python test failures[0], but will add this as soon as the
'python-tests' branch is merged.

There are a few unresolved failures still in [1], I will work on the
list (from the bottom) over the next few days.
