This is (as far as parsing goes) equivalent to just loading a page that
has "I am <script type="text/javascript" id=inner src=code.js></script>the
<b>document</b>" as the contents. When you execute the first .write(), it
starts a new parser.
However, the spec as written was a bit confusing. I've tried to clarify
it by referencing the script nesting level explicitly.
Please let me know if this is not equivalent!
