+** Testing layering of I/O

+**      The layered server
+** A thread that acts as a server. It creates a TCP listener with a dummy
+** layer pushed on top. Then listens for incoming connections. Each connection
+** request for connection will be layered as well, accept one request, echo
+** it back and close.
+**
+**      The layered client
+** Pretty much what you'd expect.
