 {{{
 < wanoskarnet> the logic of 4fd79f9def289965 is broken. you can't to call
 connection_or_check_valid_tls_handshake() just after wantread from
 ssl_read(), that doesn't means that certs recved yet.
 < asn> got_renegotiate && WANTREAD, does it for most cases
 < asn> but in certain high-traffic scenarios, indeed, the certs might not
 be there.
 < wanoskarnet> no for most cases there are no certs at all. server just
 send hello and keys and returns -1 as non blockin io (no yet answer with
 cert and finish by client).
 < wanoskarnet> callback that sets got_renegotiate happens during first
 ssl_read just after client hello.
