By this stage of the client-read, we know a GC can't start and can't be in progress. Thus even if the refcount is 0, we're still safe to read it. What's more, this area of code has never made provision for the index_lookup to return a not_found - it will crash if that happens. Thus if the implicit assumption is that the message must exist, then by the same token, we know the refcount will always be > 0
