The significance of these configurations changed during 2.1 developement 
  and they are now somewhat misleading.  As Steve notes below, the 
directory is now really a temp-upload directory.  Files from the request 
  which still exist in that directory at the end of processing are 
deleted.  So, you can technically use that directory as your permanent 
destination directory, but it really doesn't make sense to do that any 
more and I'd recommend against it.

This confused me as well.  Given the temporary nature of the uploads in 
2.1, overwrite-uploads will probably only be very rarely applied.  It'll 
be up to your action to handle duplicates now.
