Morten wrote one implementation a few years ago.

One of the big problems with lock-free is to ensure no ABA problems, and that 
requires a bit better control of the atomics than QBasicAtomic provides. In 
particular, it requires a weak mode for LL/SC architectures and it requires a 
double-pointer atomic for non-LL/SC architectures.
