No; that's not how the semantics of receiving SCM_RIGHTS messages
(which is what unp_externalize, the dom_externalize function for
AF_LOCAL sockets, is in aid of) work. The descriptors have to land in
the open-file table of the process that does the receive, regardless of
whether that process bears any relation to any process that may have
been involved at connect time.
