> 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}}.
