This behavior is very confusing for me.
I know it is difficult design problem.


This is my 1 min considered version:

  def join
    @threads.map{|th|
      begin
        result = th.join
      rescue Exception => e
        result = e
      end
      [th, e]
    } # or return Hash (th => result)
  end
