yeah, I'm thinking that if that is the case, it would allow you to create a "spike" contract, a highly funded contract designed to use a lot of miner resources until it inevitably fails. then you could send out transactions to this contract which would cause it to execute and fuck with all the other miners, where you just ignore it because you know it will fail. Maybe the cost for computation makes this unreasonable though, I don't really have a sense of the cost of computation .
