I'm not sure what you mean by tiled windows in a browser context.
Loading "about:blank" should kill anything attached to the page it
replaces in the browser window into which it's loaded, i.e. all frames,
iframes, objects, applets etc. It won't affect any new windows created
by the page, though it may be possible to find and close them with a bit
of JavaScript in an enhanced about:blank.
