[Python-ideas] Implementation of shutil.move

[David Townshend]

It seems there's a second problem too - move on remote file systems use copy
rather than rename, so changing the implementation means changing it for
copy too, which is more difficult. Maybe the best option is to try to apply
some sort of locking mechanism, but I can't see how right now.
