* The download task provides 2 pieces of functionality. The first is to process the download queue and the second is to "ping" the download queue.
* The processing of the download queue will create the archives for the bulk download action and set a flag to indicate their completion.
* The "ping" will check if the flag has been set and inform the user that the archive is ready for download.
