-            This tests whether inserting elements creates as few copies as I think
-            is possible. If this fails it just means that the container might be
-            a little inefficient.
+            This test fail because it's using unordered's internal
+            allocator traits, which doesn't work on Visual C++ 7.1.
+            It normally uses the one from Boost.Container by default.
