  21  * FetchEventOpProxyParent owns a FetchEventOpParent in order to propagate

  23  * FetchEventOpParent, but the call to Send__delete__ is handled via MozPromise.
  24  * This is done because this actor may only be created after its managing
  25  * PRemoteWorker is created, which is asynchronous and may fail.  We take on
  26  * responsibility for the promise once we are created, but we may not be created
  27  * if the RemoteWorker is never successfully launched.
