Broadcasting must happen in a certain order

[GoogleCodeExporter]

What steps will reproduce the problem?
From the experiments/interfaces directory, all on the same machine:

1. $ ./prod.out
2. $ sudo ./service.out

On the service side, I get the following output:

It is my belief that this demo is running on a mac.

Setting acceptor IP to: 10.12.19.1

***** SERVICE HANDLER ************************
   Service type:       Data Aggregator.
   Endpoint handle:    4.
   Broadcast handle:   -1.
   Connection handle:  Unset.
   My IP:              10.12.19.1.
   Remote IP:          .
   Port number:        10005.
   Interface:          en0.
**********************************************

Waiting for connections...
Cannot send broadcast: : Invalid argument
Cannot send broadcast: : Invalid argument

This does not happen if I run service.out first.  This does not seem acceptable 
to me.  It would be far better if I could run these in any order.
