    # fine.   We should update our PPA.

    # it isn't as simple as just updating all our builds to that version, though that is
    # sufficient for us to get CircleCI and TravisCI working.   We still haven't got to
    # the bottom of this issue, and are going to need to debug it in some scenario where
    # we can reproduce it 100%, which MIGHT end up being within our automation here, but
    # against a build-from-source-with-extra-printfs() of v0.4.2.

    # in the code.
