--- Comment #7 from Zebediah Figura <z.figura12 at gmail.com> ---
I suspect we don't want a fallback to have this kind of race condition on any
operating system if we can avoid it.

Could we hold an open handle to the destination, with exclusive sharing, while
performing the rename()? That would prevent any win32 APIs from writing to the
file before we do, but I'm not sure if there's any reason it wouldn't work.

If that doesn't work I guess we should fall back to copy+delete.
