Yeah Ray .. let us know if you find one!

What gets me is that the second law only applies to the progress over time of a closed system. If heat is leaving one system, it represents irreversible processes that must have consequences elsewhere. Ok, so if the fundamental laws of physics are time reversible, and yet we've just identified an irreversible process, so something's gotta give. I think this then forces us to look at what the lost heat from our system has done to all adjoining systems.
Also, from the adjoining systems' perspectives, the source of the irreversibility, has to be the processes we have just discarded because of the exclusions implicit in the second law!

Its like a dog chasing its tail, but it all leads to a break-down in the effectiveness of using the 2nd Law as a basis for making predictions.

Cheers
