Circuit list scares relay operators by using term 'exit'
When you attach arm to your shiny new relay, and it does a reachability test by making a circuit back to itself, arm labels the third hop in that circuit the 'Exit'. Which makes at least one user freak out because he thought he set his exit policy to reject :.
Perhaps arm should learn whether circuits are Internal or not (via the getinfo details), and call the final hop something other than Exit in that case?
