In the Go programming language, you can send Messages around using a construct called "Channels". http://golang.org/doc/effective_go.html#channels

I would love to use something like that in Ruby, especially for IPC.

Pseudocode of what I want:

channel = Channel.new

fork do
  3.times{ channel.send("foo ") }
  exit!
end

Thread.new do
  3.times{ channel.send("bar ") }
end

loop do
  print channel.recv
end

# ~> bar foo foo bar bar foo

Is there any construct, library or equivalent for Ruby which works like that ?

If not: What is the best way to build such an abstraction?
