 > I guess the next question is to determine if this is any worse than just
 an OS+arch fingerprinting vector, so we can decide how to prioritize this
 versus other fingerprinting issues.

 We should ask SpiderMonkey folks for a best way to fingerprint users using
 the Math object. They might know some really good corner cases due to the
 algorithms they chose. https://bugzilla.mozilla.org/show_bug.cgi?id=892671
 night be relevant here, too.
