I kinda doubt the NUMA aspect. Whether you allocate a vma that embeds a
lock, or a vma and immediately the separate lock, it's unlikely they would
end up on different nodes so from the NUMA perspective I don't see a
difference. And if they ended up on separate nodes, it would more likely be
worse for the case of separate locks, not better.
