Making it work efficiently in zope is one thing. Caching it to go
beyond imho is just not something Zope should be responsible for.

only called a few times. It's CMF that is calling it a zillion times
(why?). So it is CMF that should avoid making so many calls... if
that means caching in CMF, so be it.
