The integer class itself also has static variables, although not static integers. Will this then also be a threading problem?
Most likely. I recommend to avoid static variables. Now I have a question: What are the necessary basic data types and operations for implementing number theoretic functions and algorithms efficiently? It seems to me that a signed integer type, basic arithmetic, comparison, the modulo operator and maybe some bit shifting are sufficient. But maybe I'm wrong. However, if I'm right, I think we should concentrate on getting this right first, and then look at what's left.
