-  o Minor bugfixes:
-    - Bring the logic that gathers routerinfos and assesses the
-      acceptability of circuits into line. This prevents a Tor OP from getting
-      locked in a cycle of choosing its local OR as an exit for a path (due to
-      a .exit request) and then rejecting the circuit because its OR is not
-      listed yet. Also prevent Tor clients from using an OR running in the same
-      instance as an exit (due to a .exit request) if the OR does not meet the
-      same requirements expected of an OR running elsewhere.
-      Fixes bug 1859; bugfix on 0.2.0-alpha.
