OK, I did not know about that. However, as I know this feature was introduced in 2012 with Ivy Bridge. So, I suppose that there are still a lot of machines in the wild which does not support it. Anyway, because this code is not performance critical I am not going to insist on one or another solution. However, Andrew suggested that thing, so, please agree with him in which direction we should go. I will do what you agree.
