An entry aging mechanism would also be needed, to keep the log from
growing arbitrarily large.  Without that, entries are added but never
deleted.  If entries are aged out by date, though, there'll be times
when an aged-out entry would have made the difference between a good
restore and one which is flawed because an aged-out log entry was
needed.  The aging mechanism would need to be smart enough to
remove entries which, in light of later package operations, no
longer make a difference.
