> It would be nice to have message at DEBUG level that described all the 
> decisions we made for cache entries.  That way we could turn on this 
> debugging to get more information.  We should also store the number of bytes 
> each PBCE wanted, and the number of bytes it got, plus the number of inodes 
> it got, and output those in {{listDirectives}}.
