Re: C++0x: memory_order_acq_rel vs memory_order_seq_cst

I agree that CS is much easier to reason about because it's like

I think that situation on slide 11 is quite... unrealistic. Well, not
situation is unrealistic. Unrealistic that mentioned output can break
some real algorithm. Or I'm not right? I'm trying to figure out some
use cases for CS...

Put it this way. If you are implementing your own atomics library for
those who understand slide 11, will you include memory_order_seq_cst
or not? If yes, what is your reasoning?
