Fwiw, my testing on 30.0.1562.0 canary showed that:

  aFrozenArray.push(2);

respected frozen-ness, but, enigmatically:

  Array.prototype.push.call(aFrozenArray, 2);

did *not* respect frozen-ness; it bumped the 'length' property but did not
actually insert an element into the array.

+assertEquals(1, a.length);
+a.push(2);
+assertEquals(1, a.length);
