   // IUnknown methods so that something bad like this doesn't happen:
   //    ScopedComPtr<IUnknown> p(Foo());
   //    p->Release();
   //    ... later the destructor runs, which will Release() again.
   // and to get the benefit of the DCHECKs we add to QueryInterface.
   // There's still a way to call these methods if you absolutely must
   // by statically casting the ScopedComPtr instance to the wrapped interface
   // and then making the call... but generally that shouldn't be necessary.
