// This class needs to function even if it was built retail.  That is, a debug caller calling against a retail 
// SMDiagnostics should still have asserts fire.  To achieve that, we need to define DEBUG here.
// We do not do the registry override in retail SMDiagnostics because that would require shipping a test hook.  We 
// do not generally ship test hooks today.
