Also, just noticed your class-caching isn't keyed off user. (I'm also
honestly not sure what @ instead of @@ means inside a self. class method;
I'd have to look that up and write specs to test it!)
Something like this may work better.
@expiry_date_cache ||= {}
@expiry_date_cache[user.id] ||= find_if_expiry_date_for(user)
(Also Rails 2.something has a memoize feature which does key off
arguments--see the Railscast. Not sure if it works for class methods).
