Hmm. For one I don't think splitting the lock makes sense even for
split lists. Second, do we really need different lists, or just take
the type into account when dispatching from rq_list? I'm not really
sure about that one, but a rationale for splitting might be worth
adding to the changelog if you want to stick to the split lists.
