+    - extend the set of signals that are treated as "external",
+        i.e. if an app exits with one of these, put it in limbo
+        rather than treating it as error:
+        SIGHUP, SIGINT, SIGQUIT, SIGKILL, SIGTERM, SiGSTOP
+        Note: some of these should in principle never happen
+        because they're caught by the API.
+        But it doesn't hurt to be safe.
