Bzzzt. That *is* the way it works when you use sockets from the UNIX address
family (which is specified by the AF_UNIX argument). These are UNIX named
pipes, which create a point in the UNIX filesystem which independent
processes can read and write without having to set up a direct pipeline
between them.
See the documentation for mknod -p, IIRC.

This code is a network socket server, which unfortunately will not do what
the original author appeared to want.
