It is actually possible to dynamically detect what an out of the money option is.
Since we go backward, we just remember what the lowest payoff is, and never exercise if the early
termination value is less or equal to that value.

In this updated version of the mcbasket experimental patch, I've implemented it.
In my (simple) tests it worked properly.
