Detailed Description

A disk cache for article bodies.

This allows a cache to be set to a certain maximum size, where the oldest articles will be aged out when the cache is full.

It also has a lock/unlock mechanism to allow the cache to grow past its limit briefly to allow large multipart articles' pieces to all be held at once (for decoding).

FIXME: This should probably be an interface class implemented in data-impl in the same way profiles was.
