Lock-Free Work Stealing, Part 1: Basics

I don't see any mention of where the author mitigates, or prevents the ABA problem. https://en.wikipedia.org/wiki/ABA_problem

- Some systems will use a double-CAS where one word is a counter.

- People lucky enough to use RCU can use grace-periods.

- You can also mitigate it (to a degree) using the bottom bits of the pointer and the kernel area of the pointer as a counter.

- Also, Hazard Pointers.

The home page describes it as "the foundation for all our tools, with parts of the engine being available to licensees as stand-alone game engine bits."

This post suggests that it is intended to compete with Unreal and CryEngine:

One of the posts about runtime-compiled C++ states that iOS is not a target platform.
