+/**
+ * This class basically wraps the DiskFileItemFactory which is the
+ * default FileItemFactory for Jakarta FileUpload. The threshold
+ * setting specifies how large a file can get before it gets flushed
+ * from memory onto disk.
+ *
+ * TODO: Someone mentioned that google app engine won't let you
+ * write to the filesystem. It should be documented that you could
+ * potentially set the threshold to match your max upload size and then
+ * keep all files in memory. I don't know if it will work, since the
+ * MultiPartRequest interface insists that Files be used and I don't
+ * know what will happen, but it is worth trying.
