I'm aware of this suggestion and it's motivation. I'm not
convinced that this is the best way to address.
In your particular application, I don't think it should be necessary
to "reset" the archive as long as you're not serializating any
pointers. If one is not serializing any pointers, then no
tracking is done. So a "reset" operation should be surperfluous.
The best way to handle this is still an open question to me
