- ** 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.
