I see. So, if git pack-refs works correctly, it waits for the
sub-process, and the 'wait' in test_when_finished does not buy a lot. If
there is breakage, the trash directory is not attempted to be removed,
and it does not matter that a process potentially occupies it. I think
your version is good then.
