Ok. It's probably still worth testing Mel's patches, since that's what
goes into 3.17. But it would be interesting to eventually go back to
stability-testing the protnone set, since it *looked* like it was
working well aside from this issue. I might decide to just do it
during the 3.18 merge window..
