> Likewise for any constant response, with a couple of exceptions:
> * IF the method will *never* get implemented (ie, do we ever need
> writeable archives?) Then the message level should be LOG_BABBLE, and
it
> should say something like "Foo::Bar - I wasn't expected to be
> implemented OR used!"
* Or for virtual functions that should be abstract, but can't be (for
whatever reason). (ie io_stream::~io_stream()).
