You must not store JSObject* directly, because that doesn't play nice 
with the GC moving objects.

If you're storing JSObject** pointing into a rooted thing, that might be 
OK as long as you don't write to it, I think.  So a "JSObject* const*", 
basically.

I'm not quite sure what you're asking here... :(
