I guess if we do a fcntl(socket, F_SETFL, O_ASYNC), we may get a
notification if the socket has been connected.  This could be the
trigger to do the first TLS handshake try.  For subsequent tries, if
needed, we somehow have to rescedule them.  For example with just
another round, triggered by a short pselect timeout, like you proposed.
