-Re: Shuffling over the network for local map data.

My assumption is that unless it is reading from http://127.0.0.1/ or
http://localhost/ , it reads over the network. If I'm wrong please correct
me. The http tracker address that a ReduceTask receives is not of that
format. So I do not think it is reading using the loop back address.
