Hm, I'll have to think some more about that.

Initially just because I didn't know if it was a problem I introduced,
since I was working on making build changes. Hence I spent a good number
of minutes trying to figure out the ultimate programmer question "Did
*I* break something?". It means that each time I do the top level build
I'll have to take careful note if it's the failing test or something I
did. And as you know humans aren't very good at doing careful repetitive
tasks. So it's a PITA since it means more time I have to spend thinking
about the output, and less about what I'm trying to fix.
