<p>This test reproduces the crash in DOMWindow::clearTimeout that happens when DOMWindow is disconnected from the Frame (as in back/forward cache expiration case tested here).
<p>This is the link to the bug: <a href="https://bugs.webkit.org/show_bug.cgi?id=29832">https://bugs.webkit.org/show_bug.cgi?id=29832</a>
<p>To reproduce the crash, click the link below, the popup window opens, which will immediately navigate to another one, so the b/f cache entry will be created. Close the popup window. Wait a few seconds (~10), for the page cache to start deleting pages it doesn't need - crash will happen.<br><a href="javascript:test()">Crash me!</a>
