I tried sending the pause indicator using a variety of plausible IO
methods (write, print, puts, etc.) but without success. The receiver
listed below prints the data but only after five seconds. 

Sender:

require "socket"
require "yaml"

data = { 'a' => [1,2,3], 'b' => 43 }
server = TCPServer.new("localhost", 5555)
socket = server.accept
YAML.dump(data, socket)
socket.write "\n...\n"
sleep 5

Receiver:

require "socket"
require "yaml"

socket = TCPSocket.new("localhost", 5555)
data = YAML.load(socket)
p data
