Sorry this is wrong; we know the size of the section but the entries are 
variable size and there has to be a way to know when we have found the 
last one.

I think that flags==0 is the marker.  Have you seen any Garmin map with 
flags==0?

It seems to me that a node is either on the boundary or has arcs, or 
else it is not a routing node.
