Right, except that the semantics are different (delete on close, not 
delete immediately), so it still doesn't solve the portability problem 
in this case. Also, DeleteFile fails if the file is mmapped. From MSDN:

So in this case, I still need to do the ugly contortions to close the 
old archive before replacing it.
