What is the fastest way to concatenate two lists, destructively or not?

Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    b = [0, 1, 2, 3, 4, 5];
    a = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
  };
</script>

Test runner

Warning! For accurate results, please disable Firebug before running the tests. (Why?)

Java applet disabled.

a = a.concat(b);

while (b.length) {
  a.push(b.pop())
}

for (i = 0; i < b.length; i++) {
  a.push(b.pop())
}
