- * Helper object for APIs that deal with DOMRequests and Promises.
- * It allows objects inheriting from it to create and keep track of DOMRequests
- * and Promises objects in the common scenario where requests are created in
- * the child, handed out to content and delivered to the parent within an async
- * message (containing the identifiers of these requests). The parent may send
- * messages back as answers to different requests and the child will use this
- * helper to get the right request object. This helper also takes care of
- * releasing the requests objects when the window goes out of scope.
- *
- * DOMRequestIPCHelper also deals with message listeners, allowing to add them
- * to the child side of frame and process message manager and removing them
- * when needed.
