Very simple. Just logs things. Doesn't handle errors.

I'm concerned this doesn't support the send_area_to_processor arg of Processor

I can add that in. I don't know why it's there is all.

Will add it now.

It's there because I use the area in a lot of the processors I write and use. But I don't want to make every processor support an area argument. It does stick out a little, but it's the best option I could come up with.
