But hasn't the earlier part of this series made sure that asking
has_object() without an extra flag would make it say "no" if the
object that we know we can obtain is kept in our promisor remote
to be lazily fetched?  Or am I missing some other mechanism to make
sure that somebody does any necessary lazy fetching of an object
before we point our refs at it?

Thanks.
