I committed the change that prevents orte-submit from binding a listener - 
seems to work fine for me, so please let me know how it works for you.

The other issue - binding to all interfaces instead of only the ones specified 
- is a little more troublesome. If we don’t bind to all interfaces, then we 
have to consume a socket for each interface we are going to bind to - which 
means we trade-off binding one socket to all interfaces for consuming one 
socket per interface we are using.

It seems to me that binding to all interfaces doesn’t hurt us given that we 
will only attempt to connect on the specified interfaces, whereas consuming 
even more file descriptors can be a problem, but maybe I’m not seeing 
something. Anyone have an opinion here?
