The first concern about 5accb0ac8bfb was raised more than a week ago
and more piled up over the course of the week. I knew Raymond wasn't
offline, since he continued to commit. Since we don't have mandatory
reviews before push (which more and more I think we should),
post-facto reviews on python-checkins need to be acknowledged. A
backout is not the end of the world; it takes seconds to reland once a
conclusion has been reached. This incident should not be construed to
diminish Raymond's long history of contribution or his technical

My second reversion (86d512e0ec66) was knee-jerk and shouldn't have happened.
