Ah, this explains it. I have BOOST_THREAD_VERSION 3 explicitly defined
because I couldn't be having with some of the version 4 behavior. Which is
why I prefer boost threads over std threads in the first place.

Thanks for the heads up. I will try to re-evaluate if I should go for
version 4 after all but as I recall there were some strong reasons not to
do it. At least now I know what I'm trading in for that.
