Unless of course someone has already got code in your page that does
Object.freeze = function(){};
Same thing applies to preventExtensions, seal, create, defineProperty, etc and
of course the Object constructor itself.

It does annoy me that these were not made immutable. The safest way to create
an object is still either with an object literal or new SomeFunction;
I'm not convinced that Object.create added anything of value to the language,
and certainly wouldn't recommend
its use for general object creation.
