Class::DBI does *not* have an object cache.

It has a live objects index, which is entirely different - it's designed
to ensure only one copy of the object exists in memory at any given time.

You can turn it off by setting $Class::DBI::Weaken_Is_Available to 0.

If you actually want an object cache, try Class::DBI::Sweet.
