How to kill just about any browser in 30 seconds and leach your bandwidth to boot!

I am kind of proud of this actually. I accidentally setup a recursive/loop pattern between my php scripts, and my ajax scripts which calls an alert() and adds an element to a popup window. At first I was annoyed then I opened up the process console and watched firefox.exe slowly balloon from its normal 40 megs to 490 megs before I killed the process.
