Message 260727 - Python tracker

Thanks for the additional patch, Jesse. Since we don't have a NetBSD buildbot and I don't have any NetBSD or OpenBSD systems at hand to do any testing, I'll take your word for the version checks.  If anyone runs into any problems because of these changes, feel free to re-open this issue.  Pushed for release in 2.7.12, 3.5.2, and 3.6.0.
