Now that's an example of when I think sessions are a poor solution.  IMO
caching objects from the database is the job for the, well, database
object cache. :)

They are similar but not identical.  For instance, while session data
typically expires after a certain amount of time, permanent data should
never expire unless invalidated by an update.
