It's totally an edge case, but if everyone agrees, it will probably
get spec'ed at some point. For ES5, probably not -- up to Allen at
this point.

Here's what I observed:
Opera 9.63 - conforms to ES3/ES5 spec.
Range error on a.push(1) after creating a non-array index property named
"4294967295" and leaving length as 4294967295
Chrome 1.0.154.65 conforms to ES3/ES5 spec.
Range error on a.push(1) after creating a non-array index property nam

a.push(1)
is to create a non-array-index property of the array with name
4294967296 (i.e. 2^32) and value 1 before throwing a RangeError hen
trying to update the length. However this property isn't
