I think so. But how to actually change it is another story. This is a 
result of a change Volodya did for supporting BB configuration. So we'll 
have to see how he wants to handle it. Which mainly boils down to if we 
should include those configuration results in the test results, or not. 
He should be sleeping at the moment :-) So we'll see in 7 or so hours.

I know it's going to be painful for people.. But I guess I have to 
change bjam back to the old version until we resolve this.
