  * [rebased for 1.9.2] After a server disconnects, make the IServer retain the dead RemoteReference, and continue to return it to anyone who calls get_rref(). This removes the need for callers to guard against receiving a None (as long as the server was connected at least once, which is always the case for servers returned by get_servers_for_psi(), which is how all upload/download code gets servers). Includes test, which is now the same as on trunk. fixes #1636 for 1.9.2.
