Running wireshark reveals that gnutls sends each of the handshake
packets in separate TCP packets, but openssl combines them and sends
them in one TCP packet. I'm not sure how much overhead this generates,
but since network traffic is involved, it may be significant.
Anyway, running callgrind on these binaries would be interesting... next
step.
