A friend of mine was actually trying to crash his system at work and asked me for an idea. I gave him that code. I know what you are saying about posting it though. I though about it too late though. And I don't know how to update these posts.
I don't think its a serious problem, hopefully people will only use these things for "productive purposes". But did you click the link in my earlier post - there are dozens of amazing one liners that will bring down your system in seconds!
