After finally releasing git-annex 6 yesterday, I did some catching up today, and got the message backlog back down from 120 to 100.

By the way, the first OSX release of git-annex 6 was broken; I had to fix an issue on the builder and update the build. If you upgraded at the wrong time, you might find that git-annex doesn't run; if so reinstall it. I now have an account on a separate OSX machine from the build machine, that automatically tests the daily build, to detect such problems.
