Make an HTML page goto infinite loop?

Question

Write a code using HTML, JavaScript, jQuery to make the page go into infinite loop.

Restrictions:

No looping or control structures of javascript and jQuery allowed. You can only use alert, events, etc.

1. What's the winning condition? 2. What does it mean for a page to be in an infinite loop?
@grc: I'm not so sure it's ambiguous; a blank page doesn't require that the browser must be closed to continue. However, I don't think it's possible to do this in modern browsers. I'm not on Windows, but I can remember how to crash IE without using loops (though that may have been fixed in IE 9/10).
@Andy E: I don't really get what you mean by continue. Does it mean that you are able to use elements on the page, or that you are able to use other pages in the browser?
@grc: the OP makes it sound like he wants to lock up the browser and force it to be closed. This is difficult/impossible in browsers with sandboxed tabs, but you can crash a tab (see Florian's example).

$($);

May not meet your conditions, but I like it. (And it does crash your browser.)

How about a meta refresh?

<meta http-equiv=refresh content=1>

I removed the quotation marks around the parameter values because code golf.

This reloads the page as soon as it loads:

<html>
<head>
<script>window.location=window.location</script>
</head>
</html>

Or you could bring up infinite alert boxes (until the user disables them):

<html>
<body onfocus="alert('')"></body>
</html>

	5 years ago I would have voted on this. However, most modern browsers have a checkbox on the alert that will prevent further dialogs from appearing. – Andy E Oct 3 '12 at 8:47
	That's right. Even if you don't check it, the browser limits alerts to a specific number. Here is Google security policy that explains more about it. – Darshan Thanki Oct 3 '12 at 8:50

This will reload the browser indefinitely:

location.reload()

(Unless the browser specifically blocks repeated reloads.)
