From cf350013807bf347af29f17a4c87861c194e3e10 Mon Sep 17 00:00:00 2001

Subject: More simplification - don't pass state around.

Rather than passing our settings-object around, as well as
specific settings that are read from it, just pass the object.

The worker can read the settings directly if/when it needs to.
