It's a bit surprising that it outputs anything at all! If the above is 
your entire program, then when the program exits, the thread will be 
killed. On my system, that means no output at all. In order to wait for 
the thread to complete (before the program exits), you need to call 
'join' on it like so:

t = Thread.new do
  3.times{
    puts "hello"
  }
end

t.join

Hope this helps.
