>1. I'm not entirely convinced that this is a reasonable commit to test.  Due to the way Andrew has merged a fix for this commit in a second commit, it's expected to be buggy.  Although I don't think it could cause this specific failure pattern.  Testing commit ffc87d11841ec68a44c57735ff4fada521ab5a27 would make more sense.
