Simplifying a bit:  Run weekly(8) and monthly(8) from daily(8) instead of
from cron(8), but only when the last run is at least a week or a month
ago, respectively.  This is similar in spirit to the way security(8)
is run.

Main advantage: When your notebook is in use every N-th night,
the weekly(8) mean period decreases from 7*N days to 7+(N-1)/2 days.

Bonus: Get rid of duplicate functions in weekly(8) and monthly(8).

Side effect: daily(8), weekly(8) and monthly(8) run one after the other,
not in intervals of two hours.  In some setups, this might be a bonus,
in some others, an inconvenience.

Thoughts?
