Spawn-Tcp-Server

(spawn-tcp-server integer function) -> listener

Opens a socket at port integer. Function is evaluated when an outside connection is made.

Example:
(From Terminal "Alpha")

>> (spawn-tcp-server 9191 repl)
:: [listener 5B0410]

(From Terminal "Beta")

$ telnet localhost 9191
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

While useful as a demonstration, for practical purposes, this example is dangerously insecure, and should be avoided.
