First i see that a new event (libevent) is created with when a "connect" is made with a socket, the event type is  EV_WRITE.  why not EV_READ aswell,

 /* add to our list of monitored event sources */
                conn->ev = event_new(nci->eb, conn->fd, EV_WRITE,
                                     nc_conn_evt_connected, conn);
