Lock-free programming is a performant multi-threaded synchronization technique that allows you to safely manage in-memory data in a controlled manner. In its essence, the idea is to write your multi-threaded programs without using locks. Why is this better? For one thing, using OS constructs like mutexes will sometime induce an additional performance penalty.

For example, the occasional user-
