Note that there is at least some discussion within Mozilla about trying 
to make the prototype of Object.prototype immutable (such that 
Object.getPrototypeOf(Object.prototype) is guaranteed to always return 
the same thing, modulo someone overriding Object.getPrototypeOf), along 
with a few other things along those lines.  See 

Whether this is web-compatible, we'll see.
