Right, and since it would be good to avoid thread stuff in libgnutls, I
think it cannot be made part of libgnutls. But if someone wants to
provide code for this, putting it in a libgnutls-stream library or
similar could be done, and may be useful.
I suspect rewriting code to use normal read+write instead of buffered f*
function is simpler and more reliable though. TLS has some semantic
differences compared to network streams that may be difficult to
simulate (e.g., re-handshakes and alert messages).
