        // statement right before the last one (the return), everything is
        // returned correctly and there is no seg fault.
        //
        // I'm always very leery to call something a compiler bug.  However,

//    specification, not the pipeline specification yet.

//    I renamed Network to DataNetwork to make the Windows compiler happy.
//
//    Hank Childs, Thu Sep 12 11:11:16 PDT 2002
//    There was an issue with multiple networks sharing NetnodeDBs, so I
//    made them all have their own reference.
//
//    Jeremy Meredith, Thu Oct 24 16:03:39 PDT 2002
