This has never been a problem for me, because I haven't encountered the need 
for an infinite archive.

An infinite archive that contains shared_ptr instances should, in fact, keep 
the objects alive forever:

- read shared_ptr #28, along with the object
- reset() the shared_ptr read above
- read shared_ptr sharing ownership with #28
