One thing I see a definite use for a small object cache is in 
mod_disk_cache, to store the headers of requests. This will allow the 
update of headers without the song and dance that we have to go through 
now to do this.

Headers fit the criterion of "small" and "fixed size limits", but would 
need to be persisted across a server restart somehow, ie with DBM or DBD.
