Ok, good.

I don't know if its a problem, but the cross-origin blob URLs also kind of leak some information about when the creating context goes away.  If thats like a nested context that the current origin wouldn't know about it might be some kind of cross-origin information leakage.  Kind of weak, but nice to avoid.
