@ivar refcount: the number of times this reference has been sent to the
remote end, minus the number of DECREF messages which it
has sent back. When it goes to zero, the remote end has
forgotten the RemoteReference, and is prepared to forget
the RemoteReferenceData as soon as the DECREF message is
acknowledged.
