for eina_future, with my suggested implementation all the promises/futures will be bound to their objects. If the object dies, the futures are cancelled...
eolian should come to help and all methods returning futures should be automatically bound to the object, unless they are explicitly marked as unbound. Them these should not be calling back any of the previous object.
