Progress: controller program.

Continue working on the thread support.
As I am learning how to use threading, I am finding that my conversion is flawed in some way and somehow losing the pointer address.
I worry that this might be related to how realloc() changes the pointer address, but there is no strong evidence to this fear.

I've decided to just save the current state (regardless of its state) and will rethink the design.
Currently the behavior is more consistent but still problematic.
