Subject: use less CPU in retention-enforcer

* start it with "nice"
* put in "sleep 1" between each processing step, to make it
  less CPU intensive
* avoid doing work which can never be useful, by not looking
  at databases where the earliest possible timestamp is
  not older than the retention limit
