 This is because you have never read ruby-man-1.4, and it's very bad :-)

 The example given is

 ------------------------------------------------------------
    Even shorter using thread:

require "socket"

gs = TCPserver.open(0)
addr = gs.addr
addr.shift
printf("server is on %d\n", addr.join(":"))

while TRUE
  ns = gs.accept
  print(ns, " is accepted\n")
  Thread.start do
    s =	ns			# save to dynamic variable
    while s.gets
      s.write($_)
    end
    print(s, " is gone\n")
    s.close
  end
end
