Comment (by Craig Hutchinson <craig@…>):

 Okay so I have learnt lots of new things today. I have a pretty good
 solution wihtout the performance issue of a mutex. I think boost probably
 has a call_once too but used std in this test:


 {{{
 #include <mutex>
 ...

 static std::once_flag l_onceFlag;
 SYSTEM_INFO system_info()
 {
     static SYSTEM_INFO si;
          std::call_once(l_onceFlag,  [&]
          {
                  si = system_info_();
          });
     return si;
 }
 }}}
