Oh, I agree that the reasoning has flaws. I'm relying on probability here. I 
would bet that the probability that this is a bug is *low*, based on the number 
of people looking at the code base and knowing the competency level of the 
people looking at it. But just because the probably is low, does not mean that 
it is zero; without more information there's still a chance that this could be 
a bug, even if it is a small chance.

Very good point. Since we have this confusion, it must not be clear in some 
documentation somewhere.
