Note that today there is no contract which says that all segments returned by a `SegmentAllocator` must have the same session. While some allocators might behave like that, I think it would not be ok to force that behavior on _all_ allocators. And, we considered to add, perhaps in the future, some small subinterface, like `ScopedSegmentAllocator` which also has a `session` accessor - this would be a good return type for the arena allocator methods, for instance. But this is a move that is orthogonal to the changes described in this PR (and also not a binding one - we can add the sub-interface even at a later point w/o breaking compatibility).
