There's no mechanism for this in the SASL libraries. With GNUTLS there is
the ability to preserve negotiated session state from one TLS conenection
and used it upon opening the next connection to fast-track the handshake
phase. This doesn't allow you to pass the state for an existing connection
to a new process though and have it carry on
