[racket] network server with places?

I think places should somehow provide better support for this task.

For now, using the FFI you could use scheme_get_port_fd() to extract a
TCP port's file descriptor as an integer, dup() it, send the dup()ed
integer to another place, and create new ports using
scheme_make_fd_input_port() and scheme_make_fd_output_port() on the
dup()ed file descriptor in the new place, and then close the TCP ports
in the original place.
