Comment #2 on issue 842 by [email protected]: Object.freeze() throws
exception is Object or Array has been extended
http://code.google.com/p/v8/issues/detail?id=842
This has been fixed in bleeding edge revision 5350.
Problem was that the loop freezing the individual properties was using "for
var in", which would include any properties introduced on the Object or
Array prototype. Simply changing this to loop using the length fixed this.
