We know it's OK here because the earlier call to _at() would have extended the slab. But it probably makes sense to use _at() in both places then (or even to use _peek() for the earlier one if you want to avoid extending, but as I said in the other message, I kind of suspect most of these cases end up allocating slab space for most of the commits anyway). -Peff
