I'll break that out into a separate patch when I reroll.

I had thought that it did, but some testing shows that it does not (or
at least does not yet).  The original series of patches was assembled
out of a long process of making the test suite pass with the alternate
ref backend.  I expect that as I rewrite that series, I'll either figure
out what issues these change solved, or remove them.  In this case, I'll
split the patch.

cruft, will remove.
