Comment(by asn):

 <asn> wrt #4312, it does *not* seem to work in the bufferevents case.
 <asn> I'm not sure how SSL is handled in USE_BUFFEREVENTS
 <asn> and I suspect it's handled by libevent
 <asn> because I don't see connection_or_handle_event_cb() getting called
 after the
       initial SSL handshake.
 <asn> so I suspect that libevent is internally calling SSL_read() or
 SSL_write(), is completing renegotiations and is not reporting back to
 tor.
 <asn> The renegotiated callback in the bufferevents case is called from
                connection_or_process_inbuf()  when the first SSL data
 packet arrives.
