Currently log-delete uses a lot of memory when running. See if we can reduce this.
When running against a large DB, it seems to use about ~800MB of RSS. With this patch it uses ~150MB. To reduce this even further, after this patch is deployed, we could run the log-delete script daily. http://gerrit.beaker-project.org/#/c/1241/
Beaker 0.9.2 has been released.
