+// This is a basic concrete implementation of CodeModules.  It cannot be
+// instantiated directly, only based on other objects that implement
+// the CodeModules interface.  It exists to provide a CodeModules
+// implementation a place to store information when the life of the original
+// object (such as a MinidumpModuleList) cannot be guaranteed.
