Not relying on non-supported semantics to save your ass.

Rename() is atomic in the sense that you either see the
old name or the new name, but I don't know of systems
which guarantee atomicity across a system crash.

In fact, knowing how hard disks work mechanically, only
journaling filesystems could have an extention to make
this work.  Ie. this is NOT something you can rely on ;)

Rik
