  # Initialize a thread-safe queue for passing output from the IO threads
  # back to the main thread
  # 
  # NOTE  This used to be done in {#start}, but I was seeing intermittent
  #       failures on Travis from what look like thread race conditions,
  #       guessing that it's from output arriving before {#start} is
  #       called, which totally looks like it could happen.
  #       
  #       See the failure in
  #       
  #       https://travis-ci.org/nrser/qb/jobs/348609316
  #       
  #       Really, I'm surprised I haven't hit more issues with this
  #       half-ass threading shit.
  #       
  #       Anyways, I moved the queue creation here, see if it helps.
  # 
  @queue = Queue.new
  
  # Flag that is set to `true` when {#start} is called.
  @started = false
