Multiple Workers One Sink

We want to gather data created by multiple Workers.

First we create a Queue:

sink = Queue.new

Then 16 workers all generating a random number and pushing it into sink:

(1..16).to_a.map do
  Thread.new do
    sink << rand(1..100)
  end
end.map(&:join)

And to get the data, convert a Queue to an Array:

data = [].tap { |a| a << sink.pop until sink.empty? }
