Comment (by viboes):

 Would it be enough to return


 {{{
 return hardware_concurrency();
 }}}


 instead of returning 0 in

 {{{
     unsigned thread::physical_concurrency() BOOST_NOEXCEPT
     {
 // a bit too strict: Windows XP with SP3 would be sufficient
 #if BOOST_PLAT_WINDOWS_RUNTIME                                    \
     || ( BOOST_USE_WINAPI_VERSION <= BOOST_WINAPI_VERSION_WINXP ) \
     || ( defined(__MINGW32__) && !defined(__MINGW64__) )
         return 0;
 #else
 }}}
