Weird. I'm not sure if that's relevant, but from what I understand, the proxy I
used does a bit more than that, eg when the server resends its ServerHello
flight, messages are reordered, and some of them are even "lost".

Sure, here it is (I hope attachments are ok for the list, otherwise I'll
resend). The client invocation was

	gnutls-cli -u --insecure -p 5556 127.0.0.1 -d 6 > cli-d6.log 2>&1

The testing plaftorm is GNU/Linux.
