When you create a thread, the main threads continues. In you case the main 
thread terminates after calling "Thread.new" so the program exists.

If you want to *wait* all the created threads to finish their work, then you 
must "join" them:

  my_thread = Thread.new do .... end
  do other stuff in main thread
  my_thread.join
