After a clone, packfiles are read-only by default and "mv" to replace the pack with a new one goes interactive, asking if the user wants to replace it. If one is successfully moved and the other is not, the pack and its idx would become out-of-sync and corrupts the repository. Recovering is straightforward -- it is just the matter of finding the remaining .tmp-pack-* and make sure they are both moved -- but we should be extra careful not to do something so alarming to the users.
