(rearranged to bottom-post)

The problem is:

trash directory.t7063-status-untracked-cache$ diff trace trace.expect 3,4c3,4 < directory invalidation: 1 < opendir: 1 ---

I can repro on a SSD.

I had to try many times to reproduce (I think even more the second time). I just ran the test in a while loop until it failed.

I suspect that the kernel might be a bit slow to update the mtime on the directory, but I have not yet been able to repro, and I don't understand why it only happens in this one test, since sparseness should be completely unrelated.
