Progress: controller program, address issues with invalid reads/writes.

I have finally identified the cause of the confusing invalid reads/writes.
It seems that using the pointers to memory address directly associated with the thread data and then accessed within a fork() call is a problem.
By copying the data to variables local to a function and then using that memory address, the read/write problems go away.

This commit only performs an immediate fix for the current problem.
What I really need to do next is to rewrite/restructure much of the code with this behavior in consideration.
There were a lot of experimental changes I performed while trying to identify this problem.

There are still some additional locking and other thread problems to solve.
These will hopefully be fixed by the planned rewrite cleanup that I need to do.
