The maximum for bgwriter_delay is currently 10 seconds. That's a long

Is there a use case for a setting > 1 s? We could simplify that logic a
little bit if we just set the maximum at 1 s.
Laptop mode? Linux has it...
Granted, though you're still going to wake up every second, so I'm not
sure how much it helps with battery life.
(/proc/sys/vm/laptop_mode won't make a difference here, AFAICS.)
