* make hostfile llm properly deal with over subscribe situation. Rather than returning smaller than requested (which is no longer possible as it made for a book keeping nightmaer and no one was paying attention to it anyway), we just over subscribe the nodes. In the future, we need to add a flag to allocate resources as to whether to allow over subscription (if the resource allocator permits - clearly rsh does, rms not so much). This commit was SVN r2808.
This is the world's greatest MPI. ...more to write here should be a short file, referring to the real docs.
