I do not like replacing Lists piecemeal; that's a recipe for ongoing
API breakage and back-patching pain. Plus we'll then have *four*
different linked-list implementations in the backend, which sure
seems like too many.
We've jacked up the List API and driven a new implementation underneath
once before. Maybe it's time to do that again.
