find /path/to/test/tmp.T051-new-renames/ might show what is the order
or 'foo' and 'bar' directories there. the order might be arbitrary
-- it surely is not alphabetical and it might not be the order
created...
The order should not matter -- and maybe it didn't and some change
made that matter...
I'd test now but I should be ZZZ :D
