Okay, I get to eat my own dogfood.  The problem in the csma code follows,

  NodeContainer c;
  c.Create (3);
  NodeContainer c0 = NodeContainer (c.Get (0), c.Get (1));
  NodeContainer c1 = NodeContainer (c.Get (0), c.Get (2));
  ...
  InternetStackHelper internet;
  internet.Install (c0);
  internet.Install (c1);

The zeroeth node created in container "c" gets internet.Install()ed twice. 
Tom's check detects for duplication of the stack itself, but misses the packet
socket factory aggregation in the helper itself.

I'll start fixing all of this if we agree that the "assert and fix" approach
advocated by Mathieu and (sigh)me is the way to go.
