     if (!we_are_hibernating()) {
       if (retry_all_listeners(replaced_listeners, new_listeners) < 0) {

         goto rollback;
       }
     }
     if (options->DisableNetwork) {
       /* Aggressively close non-controller stuff, NOW */
       log_notice(LD_NET, "DisableNetwork is set. Tor will not make or
 accept "
                  "non-control network connections. Shutting down all
 existing "
                  "connections.");
       connection_mark_all_noncontrol_connections();
     }
 }}}

 It isn't sufficient to simply not call the first part when DisableNetwork
 is set, because of the case where we want to open new control ports. But
 it looks like we're just opening them all, even when in the next clause
 we'll close (most of) them again?
