It's useful to allow authd to run in parallel with ssl negotiation, but if the ssld connection has plaintext data ready for reading there's a race condition between authd calling read_packet() and ssl_process_certfp() storing the certificate fingerprint. This scenario would be bad for a server connecting because fingerprint verification will fail. Allow either operation to complete first, but wait until ssl_process_open_fd() calls the ssl open callback before calling read_packet().
