   o Minor bugfixes:
     - Fix compilation on OSX 10.3, which has a stub mlockall() but
       hides it. Bugfix on 0.2.2.6-alpha.
+    - After we free an internal connection structure, overwrite it
+      with a different memory value than we use for overwriting a freed
+      internal circuit structure. Should help with debugging. Suggested
+      by bug 1055.
