What we do in this patch goes out the window in patch
10. This is just a temporary stage along the way to
what we have at the end of the series, needed to make
sure we don't break bisect partway through the series.

I'm not sure we should be doing much with this patch.

I could fold it into the next patch, but that would
make things harder to read.
