Note that I was mainly responding to the comment about std::thread using pthread internally. Not only is that not necessarily true, as the platform may not even have pthread, in those cases where it is true it's also true of the implementations of all other languages. How does Java do threads on UNIX other than by sooner or later calling pthread? I totally agree that sockets is a long overdue oversight in the language.
