(or the user list depending on auth mode and configuration) are initiated

+/* Map is meant to be similar in usage to ES6 Map, which is
+   described at http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets,
+   without requiring more than ES5 + Gjs extensions.
+
+   Known differences from other implementations:
+   Polyfills around the web usually implement HashMaps for
+   primitive values and reversed WeakMaps for object keys,
+   but we want real maps with real O(1) semantics in all cases,
+   and the easiest way is to have different hashers for different
+   types.
+
+   Known differences from the ES6 specification:
+   - Map is a Lang.Class, not a ES6 class, so inheritance,
+     prototype, sealing, etc. work differently.
+   - items(), keys() and values() don't return iterators,
+     they return actual arrays, so they incur a full copy everytime
+     they're called, and they don't see changes if you mutate
+     the table while iterating
+     (admittedly, the ES6 spec is a bit unclear on this, and
+     the reference code would just blow up)
