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