Ironically, I've dropped Chrome on Windows because of the very same issue several years ago. There were more than a few sites like this; the only way to close the tab was killing the entire browser with the task manager. I've been occasionally stumbling upon sites like this for a year and a half, and the bug hasn't been fixed this entire time. Then I switched to Firefox, which has a feature to bail out from the endless loop (the 'Prevent this site from creating additional dialogs' checkbox), and never looked back. So I guess there's more than one way to aggressively keep the tab open.
