--------------------+--------------------
 In {{{_libssh2_packet_add}}}, called by {{{_libssh2_packet_read}}},
 a call to {{{_libssh2_packet_send}}} that is supposed to
 send a one-byte message {{{SSH_MSG_REQUEST_FAILURE}}} will
 send an uninitialized byte upon re-entry if its call to _send
 returns _EAGAIN. Suggesting
 {{{

                  if (want_reply) {
 + libssh2_packet_add_jump_point5:
                      unsigned char packet = SSH_MSG_REQUEST_FAILURE;
 - libssh2_packet_add_jump_point5:
                      session->packAdd_state = libssh2_NB_state_jump5;
                      rc = _libssh2_transport_send(session, &packet, 1,
 NULL, 0);

 }}}
