I can think of a couple of different ways to try and account for this 
problem, none of which stands out to me as the best way, so using 
whitebox to skip the test seems okay.

Ideally we would have a simple way to filter the passed through options 
so that we could remove problematic ones for a given test, or add new 
flags to override the problematic ones.

Thanks,
David
