The reason it doesn't work is that _rename detects the case where both 
its arguments are actually the same file, or look like the same file 
(which included the case, until my recent commit), and if so, it does 
nothing.  So the file is not renamed.

I'm at a loss why the code snippet you posted works; it shouldn't.
