49 GnuTLS is configured to use custom push / pull functions:

50 - the pull function retrieves the data from the fifo queue corresponding to a stream #.

51 - the push function sends the data on a certain stream.

52 We also have a demux thread that reads the socket and store received data in the appropriate fifo

54 We have one gnutls_session per stream pair, and as many streams that read the gnutls records and save incoming data to the target queue.

56 This complexity is required because we cannot read a socket for a given stream only; we can only get the next message and find its stream.
