This has comes up before too. My thoughts are basically that since it's
just a few blocks of code (I think we're discussing less than 200 lines
of code split over nine files here) it's hard to see why it would be
such a burden to carry those blocks in a separate tree until everything
can be submitted in actual working condition.
