Many unsafe memory operations #78
Description
This project does a lot of pointer-fiddling casts and dereferences that may violate memory safety. In many cases I am still figuring out the right interface to model memory etc., see issues like #23 and #26, and worrying about safety additionally isn't useful yet.
I would like to fix them someday. Per Rust they are all in "unsafe" blocks and easy to grep for. I created this bug just to fold others into it.
