Note: the code in this directory is not tested and not even completed.
Based on Steve's suggestions, I (Paolo) have decided to get TCP objects
back in 1.7, with new classes roughly based on Java Sockets. I don't
like Java itself, but its socket classes are good, and after all they're
well understood.

I've made it more 'Smalltalk'. For example, the Java SocketImplFactories
have been replaced by a defaultImplementationClass class-instance variable
(a new feature in 1.6).

Here is the hierarchy, which should not change:

Object
    ContentHandler
    Datagram
    IPAddress
    (PositionableStream)
        AbstractSocket
            Socket
            DatagramSocket
                MulticastSocket
            ServerSocket
        (ReadStream)
            ReadBuffer
        (WriteStream)
            WriteBuffer
            (ReadWriteStream)
                UnixStream
		    AbstractSocketImpl
                        SocketImpl
                            TCPSocketImpl
                        DatagramSocketImpl
                            UDPSocketImpl

Everything is written, but I've not tested anything yet.
