> Why do you care whether an about:blank page is modified?

That's the point at which it is no longer safe to show the pending URL in a newly created tab.  If you create a new tab with a slowly loading URL, we'd like to be able to display the URL in the address bar (http://crbug.com/9682).  However, a URL spoof exploit becomes possible if another window modifies the about:blank page before the slow page commits.
