Well, _if_ it does. What is actually happening is that you load a graphic
with a massive resolution. Linking to a page with a 4400 MB jpeg isn't
exactly what I'd call a DoS, but the effect sure looks like it though ;-)

However... maybe I was jumping to conclusions too quick...
Since, for the record, Mozilla on linux doesn't suffer anything.
Or so it seems.
