  10    The helpers always consist of three functions:
  11
  12    * A request setup function that takes the necessary parameters together
  13      with a continuation function that is to be called upon completion
  14
  15    * A private continuation function that is internal only. This is to be
  16      called by the lower-level functions in do_async(). Its only task is to
  17      properly call the continuation function named above.
  18
  19    * A worker function that is called inside the appropriate child process.
