allegrocache and persistent object storage

Anybody tried Franz's Allegrocache? I have been using my own rather
simple serialization methods that dump code that generates a copy of
the data structure when loaded back. Great for paging things out of
RAM, caching things that are expensive to compute and will be needed
again. Am wondering if there is a more general implementation of
serialization somewhere, and how does Allegrocache compare to that.

Thanks.
