I might be more interested if I more clearly saw your proposed design and
solution. Could you provide a brief code example, even if it is just
pseudo-code, and detail exactly what the user witnesses (I.e. when
destruction occurs, etc.)? As well, what is the "non-standard"
initialization you speak of?
