commit 852fd1819e911dfafef624640d9b54157073c326 Author: Nick Mathewson <nickm@torproject.org> Date: Tue Mar 25 10:14:26 2014 -0400 Free placeholder circid/chan->circuit map entries on exit In circuitlist_free_all, we free all the circuits, removing them from the map as we go, but we weren't actually freeing the placeholder entries that we use to indicate pending DESTROY cells.
