Thanks Bob, perhaps I've not been paying close enough attention, but it's
unclear to me how this patch set relates the the most accute issue we have
at the moment, which are the problems introduced here:

Could we begin with one patch that's easy to track that directly resolves
the issues with that commit (perhaps even a revert if it's not simple to
fix directly)?  That brings us back to a known-good place, from which we
can look at cleanups and changes.
