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.
