+    General note on cleanup environment functions.
+
+    It is expected that there is only one instance of the code signer server
+    running for a given input/output directory, and that it serves a single
+    buildbot worker.
+    By its nature, a buildbot worker only produces one build at a time and
+    never performs concurrent builds.
+    This leads to a conclusion that when starting in a clean environment
+    there shouldn't be any archives remaining from a previous build.
+
+    However, it is possible to have various failure scenarios which might
+    leave the environment in a non-clean state:
+
+        - Network hiccup which makes buildbot worker to stop current build
+          and re-start it after connection to server is re-established.
+
+          Note, this could also happen during buildbot server maintenance.
+
+        - Signing server might get restarted due to updates or other reasons.
+
+    Requiring manual interaction in such cases is not something good to
+    require, so here we simply assume that the system is used the way it is
+    intended to and restore environment to a prestine clean state.
