   o Minor bugfixes (v3 directory protocol)
     - Delete unverified-consensus when the real consensus is set.
+    - Consider retrying a consensus networkstatus fetch immediately after one

   o Minor bugfixes (controller):
     - Don't reset trusted dir server list when we set a configuration option.
