I'm not sure if this is something you have to handle or the mogilefs
infrastructure does, but if you have defined multiple replicas for a
specific domain does this work like it should (I would assume that it
would return multiple nodes then)? Is it your modules responsibility
or does the tracker and it's processes handle distributing the files
amongst the other replicas?
