Try something like this:

x = 1
threads = []

10.times do |i|
  threads << Thread.new(x) do |my_var|
    if my_var < 5
      my_var = 10
      sleep(0.05)
    end

    puts "thread #{i} executing"
  end
end

threads.each do |thr|
  thr.join
end

--output:--
thread 4 executing
thread 3 executing
thread 2 executing
thread 1 executing
thread 0 executing
thread 9 executing
thread 8 executing
thread 7 executing
thread 6 executing
thread 5 executing
