Crash of 2008?

With the way stocks have been selling off lately I don't think it is out of the realm of possibility that the NYSE could halt trading if the current selloff continues. As a rule, the NYSE will halt trading if there's a 10% drop in value by 1pm of any trading day (there are other scenarios too). As of right now, that's a 755 point drop... which has happend in the past 6 weeks. I've become so used to major down days but the continued selloff is going to make me more aware of the drops.
