I really wish you German HPC guys would stop cherry picking and 
twisting my words to suit your incessant point scoring. I find it 
disrespectful, petty and juvenile, and I am sure so do most people 
here. So please stop it. If you do it again Andreas, you will see no 
further replies from me to anything you say, same as Hartmut.

Let me repeat:

Boost.Outcome provides a fairly standards conforming Concurrency TS 
implementation with excellent performance characteristics if you 
accept the restrictions it requires, which are minor and not a 
problem for AFIO's needs.

That has nothing to do with Boost.AFIO which uses a shared_ptr to 
manage its handle object. I have benchmarked the addition of the 
shared_ptr as adding around a 0.5% overhead to handle creation. The 
increment and decrement overhead per operation was unmeasurable.

I have repeated myself enough times now I am done. Either accept the 
fact you are making hay out of nothing for the sake of noise and move 
on, or please be quiet. We're done on this point.

Niall
