Olivier's varnish instance's ban lurker is evaluating ~1M bans/s, which is a
normal rate. The instance at hand was not configured to use the cutoff. The ban
regular expressions can be optimized, but that will most likely not avoid the
problem. Other options I proposed:

- reduce the number of bans
- reduce the number of objects
- use the cutoff
- sponsor more research and possibly development to further improve ban lurker
