+  Cleanup of Old Entries
+
+    We should periodically scan the wallet for host-based entries for hosts
+    that aren't in NetDB.  Rather than removing them immediately, wait

+    purge them.  Send notification of the hosts that are being purged (and
+    maybe of the hosts that will be purged soon if nothing happens).
