Thanks Nick,
This is *almost* what I want. I want to MERGE $stdout, $stderr and my 
debugging output.  If I change @captured_io to @@captured_io and move it 
outside Initialize, does everything else stay the same?

The only changed section is then:
    class OutputCapture < DelegateClass(IO)
      def initialize(io, &assign)
        super
        @delegate_io = io
        @assign_block = assign
        @assign_block.call self
      end

      @@captured_io = StringIO.new

Also, in your invocation on line 50, is {|io| $stdio = io} only used for 
resetting $stdout back to normal. Nothing else?
