require 'socket'

tcp_client.write "Hello World"
puts "finshed writing"

session =3D tcp_server.accept
puts "we recieved: <#{session.gets}>"



Why doesn't that work?

Or, a threaded version:

require 'socket'

t =3D Thread.new do=20
tcp_server =3D TCPServer.new 'localhost', 4321
while (session =3D tcp_server.accept)
puts "we recieved: <#{session.gets}>"
end
end

tcp_client =3D TCPSocket.new 'localhost', 4321
tcp_client.write "Hello World"

t.join

Still doesn't work though. What am I missing?

Aha. I'm guessing it has something to do with not sending the data
immediately. If I do

tcp_client.close

Then the data gets sent. But I don't want to close the socket. And
I'm not seeing anything (yet) that would let me immediately send (I
tried IO#flush) the data over the socket.
