13 * A downloader is a special implementation of a nsIStreamListener that will
14 * make the contents of the stream available as a file. This may utilize the
15 * disk cache as an optimization to avoid an extra copy of the data on disk.
16 * The resulting file is valid from the time the downloader completes until
17 * the last reference to the downloader is released.
