I think there will be a big (and probably long) "huh?" moment when running the
code:

threads.each do |th|
  # send the terminator and wait
  queue.enq queue
  th.join
end

is more likely than not to never terminate. If another thread than th is eating
the terminator th.join will wait for a long time.

never ever think wisdom will protect you against threads :) except if wisdom
tells you not to use them.
