This is not relevant to the example I showed. We have a de-facto 
standard with SpiderMonkey that protects an object from having its 
[[Prototype]] changed once it has cut itself off from Object.prototype. 
Reflecting __proto__ as an accessor breaks this guarantee.

Does this matter? Clearly, it does cross-frame in the web embedding, and 
perhaps there is a narrower solution for that case. But we should 
consider carefully the full impact.
