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