Are you accusing me of lying?

I did that probably 100 times. And that isn’t even “the proper test”. Both 
clean and incremental are needed which I did. zfs snapshots help a lot there. I 
just never ran “_cleanobj” which does a full tree walk of clean. But I ran make 
clean in some subdirs many times.

I took 0 shortcuts. As I said I *forgot* that case, among hundreds of cases.
You’re welcome to do this work if you want. I guarantee you would not have 
tested even half of what I tested. 

Hey can you fix universe to only build clang once please? I’ve been working up 
to that but I think you’re best to do it.
