Do we need to add this? I mean, isn't it enough to add the macro to only
persistent handles that cause the leak? We want to limit the place where
mysterious macros are added to the code base.

This is the persistent handle that causes the leak. We can't add it to the
typedef because that is not the field of an object.

     DatabaseResourcesHeapMap m_resources;
     bool m_enabled;
 };
