Given how Actix was used for benchmarking, I'd imagine that there was a reason the original developer wanted to use unsafe a lot. Nginx was written in pure C, and that is an act of wizardry. I can't imagine wanting to do any work for a language with a 'community' full of people eager to flame or do worse things to developers who don't meet their pompous definition of safety.

`ptr`, `addr` and `cast` are the only ways to introduce unsafety, as I understand it. You have to run three greps, but you can definitely grep.
