Try running procexp to see if it can see what's happening to the
handle. It's possible it's a virus checker / indexer, although
they'd tend to allow the file to be deleted out from under them.
It's not quite clear from your description above whether you
can be sure that the called subprocess has closed all its handles
by the time the os.rename runs.
