I don't think that json should be unbundled. It is the interchange

Only seems to hang if the et or ot threads are joined in the popen3 block.

Does not hang even with n > 1000 (though ruby segfaults with n > 2000):
          #ft = Thread.new{ sleep 5}
          et = Thread.new{ e.read }
          ot = Thread.new{ o.read }
          #et.join
          #ot.join
          #ft.join

          ft = Thread.new{ sleep 5}
          et = Thread.new{ e.read }
          ot = Thread.new{ o.read }
          #et.join
          #ot.join
          ft.join

Hangs:
          et = Thread.new{ e.read }
          #ot = Thread.new{ o.read }
          et.join
          #ot.join

          #et = Thread.new{ e.read }
          ot = Thread.new{ o.read }
          #et.join
          ot.join

          et = Thread.new{ e.read }
          ot = Thread.new{ o.read }
          et.join
          #ot.join

          et = Thread.new{ e.read }
          ot = Thread.new{ o.read }
          ot.join
          et.join

(I was going to try with file instead of pipe reading but then I
forgot I was going to try that, so I didn't yet :-)
