[julia-users] how to properly dis-connect from a TcpSocket

[Ben Arthur]

i'm able to setup a connection and pass messages, the problem is that when 
the sender is another julia process, and that process exits, the receiver 
is spammed with an infinite number of empty lines. how does one exit 
cleanly? is there a disconnect() command?  code below. thanks

========== first do this in one julia process ==========
julia> @async begin 
  server = listen(2001) 
  while true 
    sock = accept(server) 
    @async while true 
      println(strftime(time())*": "*readline(sock)) 
    end 
  end 
end

julia> Tue Dec 23 07:43:28 2014: foo 
Tue Dec 23 07:43:29 2014:

========== then do this in a second julia process ======
julia> sock = connect(2001) 
TCPSocket(open, 0 bytes waiting) 

julia> println(sock,"foo") 

julia> <ctrl-D>  # note all the output in the process above following this
