+    When an object is deleted its namespace is deleted, and all objects it is
+    mixed into are also deleted.  If the object has been renamed into the
+    namespace of one of the objects it has been mixed into, the routine for the
+    object might get entirely deleted before the namespace of the object is
+    entirely deleted, in which case the C routine the performs the namespace

+    disappear until that routine is finished.
