Subject: Error while trying to use Socket#accept_nonblock

Pretty much sample code included with ri docs:

 #Server
 # In one script, start this first
 require 'socket'
 include Socket::Constants
 socket = Socket.new(AF_INET, SOCK_STREAM, 0)
 sockaddr = Socket.sockaddr_in(2200, 'localhost')
 socket.bind(sockaddr)
 socket.listen(5)
 begin
   client_socket, client_sockaddr = socket.accept_nonblock
 rescue Errno::EAGAIN, Errno::ECONNABORTED, Errno::EPROTO, Errno::EINTR
   IO.select([socket])
   retry
 end
 puts "The client said, '#{socket.readline.chomp}'" #line number 14
 client_socket.puts "Hello from script one!"
 socket.close

#client
# In another script, start this second
require 'socket'
include Socket::Constants
socket = Socket.new(AF_INET, SOCK_STREAM, 0)
sockaddr = Socket.sockaddr_in(2200, 'localhost')
socket.connect(sockaddr)
socket.puts "Hello from script 2."
sleep(2)
puts "The server said, '#{socket.readline.chomp}'"
socket.close


When i run the above code, the server code exits with an exception :

non_block_server.rb:14:in `readline': Transport endpoint is not
connected (Errno::ENOTCONN)
        from non_block_server.rb:14


Any ideas, why?
