[mpich-discuss] mpich startup without networking

[Balaji, Pavan]

That's gross.  I think nemesis has the same problem that I just fixed in Hydra.

The correct solution is to move this check for localhost/local IP to MPL and use it in both places.  I'm in the middle of a different code hack right now and can't context switch to this, unfortunately.  But given that you have a workaround for now, I've created a ticket for it and will deal with this later.
