Just to be sure, you mean that two threads sending at the same time is not supported, not sending & receiving from 2 different threads.

In which case that should work for us, the creation of receiver/sender threads should act as the required memory barrier (since we spawn the threads after the `gnutls_handshake` call returns); at least as far as the `recv_state` variable is concerned; but then I'm not sure this would work for `initial_negotiation_completed` since it would be modified by the thread completing the handshake at a later time right?
