Ouch, ouch, ouch. There's no need to do this. Just do what you'd do in
C -- bind to port 0, and let the system choose a port for you:

s = TCPServer.new('0', '0')   # Bind to all interfaces, with any port

(a quick grep through netstat shows that I got port 48944 this time).

The client classes (TCPSocket, etc.) will have a port allocated
dynamically in the same way.
