    1.10 + * This template class can be used to implement the singleton pattern.
    1.11 + * The underlying object will be destroyed automatically when the process
    1.12 + * exits. Note that, if you call Singleton::Get again after the object has
    1.13 + * been destroyed, the object will be re-created which will result in a
    1.14 + * memory leak as reported by most memory leak checkers. It is up to the
    1.15 + * user to ensure that Singleton::Get is never called from a static variable
    1.16 + * finalizer.
