+
+ 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.
