I suspect this means one of two things:

1) The timeout was reached.

2) The socket is in non-blocking mode, and then you need to call the
gnutls_handshake function repeatedly until it either returns
successfully, or fails, or the timeout is reached.  I dont know whether
the python-gnutls wrapper is expected to do this or whether your python
application code is expected to do it.
