I have two programs, a server and a client. I want to send two messages
to the client when the client connects to the server, with a delay in
between. However, both messages seem to arrive at the client at the same
time. Here are the programs:

## simpleserver.rb
## run this first
require "socket"
server = TCPServer.new(2000)
while connection = server.accept
  connection.write "one\n"
  connection.flush
  sleep 1
  connection.write "two\n"
  connection.close
end

## client.rb
## run this second
require "socket"
sock = TCPSocket.open("localhost", 2000)
while not sock.eof?
  print sock.read
end
