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.
