+// FIXME-VC6: VC6 has troubles with template methods of DLL-exported classes,
+//            apparently it believes they should be defined in the DLL (which
+//            is, of course, impossible as the DLL doesn't know for which types
+//            will they be instantiated) instead of compiling them when
+//            building the main application itself. Because of this problem
+//            (which only arises in debug build!) we can't use the usual
+//            RegisterAndRestore(obj) with it and need to explicitly create the
+//            persistence adapter. To hide this ugliness we define a global
+//            function which does it for us.
