I agree that you have to put it in head and live with some breakage
before you'll get test coverage.
What's wrong here is that it shouldn't go into head until it at least
passes a minimum of tests off head.
My approach, in a volunteer, distributed project like this one, is
commonly used and results in a lot of things making it into the tree.

Fundamentally, you've missed a state. There's "far too broken",
"broken", and "less broken." If you introduce "far too broken" code
into current, your desire for user testing backfires as people move
away from it because it's too unstable.
It should be a ground rule of any project that you don't introduce
code if you know it breaks architectures and you supposedly have those
In fact, as long as you know it's broken, you shouldn't introduce it,
even into current.
Given that he knew that newlock2 was broken, Andrew should have never
committed it. You commit feature breaking changes _after_ you've
fixed all the bugs you can find on your own, not before.
