title: Where does PERSISTENT file system storage store with chrome?
body: <p><a href="http://www.html5rocks.com/en/tutorials/file/filesystem/">When doing <code>webkitRequestFileSystem</code> in <code>window.PERSISTENT</code> option</a> in Google Chrome, where on my filesystem do files get written?  I'd like to drop files there and have Chrome interact with them while I'm building and debugging this app.</p>
