Comment 10 for bug 1445619

I've prepared the Twisted backport (see https://code.launchpad.net/~cjwatson/launchpad/twisted-13.0.0-p2/+merge/277642). launchpad-dependencies has been upgraded, I've landed the txpkgupload pip changes, and I've upgraded txpkgupload to testtools 1.8.1 and Twisted 15.4.0 (though only currently on dogfood). So I think I'm now just awaiting review of my Twisted backport plus the release of Twisted 15.5.0.
