+
+	// It would probably be overkill to permanently maintain all these lists
+	// for all maps, so we could only set them up for the current map.
+	// (which makes me wonder if there should be a separate class for the
+	// active map?)

+	// (Note that we probably won't even have all items permanently stored,
+	// since fixed items will be cached out most of the time)
