Well, I was trying to ignore the store in this question at this point
-- could be memcached or BerkeleyDB or something else.

I'm more curious about the issues dealing with freezing and thawing
CDBI objects.  Specifically how to make sure I'm not storing more than
needed and if there are other "gotchas" to be aware of.  For example,
deflating and inflating DateTime object when serializing.
