title: Portable way of setting std::thread priority in C++11
body: <p>What is the correct way in the post C++11 world for setting the priority of an instance of std::thread</p>
  
  <p>Is there a portable way of doing this that works at least in Windows and POSIX (Linux) environments?</p>
  
  <p>Or is it a matter of getting a handle and using whatever native calls are available for the particular OS?</p>
