Then your test differs from the one I originally posted, or you're 
running it on some ancient hardware. The "original" test will take less 
than a second in Mozilla, several seconds in IE, but it doesn't 
hang/kill any browser (at least not on any computer where I'm at right now).

Kind of hard to avoid when running tests like this, isn't it?

Ruby, PHP, Perl, the list goes on.
