27 // implementation detail of whether destruction is implemented
28 // by a specific destructor or by inheritance. Oh well.

31 // superclass destructor gets called anyway (I think that only
32 // works when you _don't_ define a destructor so that the default
33 // one pertains) or whether I need to duplicate the functionality
34 // of that destructor. Let's play safe by assuming the latter and
35 // zeroing what we free so that we get bitten if we're wrong.
