The problem is that a rename or move on the same disk is significantly
cheaper than one that crosses disks.  It's also a much safer
operation.  I think the implementation detail line is quite fuzzy
here.

More generally, the destination might not even be a disk filesystem;
it could be a remote ftp site or /proc on Linux.  Does a move/rename
even make sense in those cases?
