Touché. But, still - without any firm evidence I believe that "C++ -> pthreads layer -> Win32 threads" is slower than "C++ -> Win32 threads", which is what I based my assumption upon.
Makes sense in the absence of any other information. But the key point here is that 'C++' is essentially the same as 'pthreads' with a C++ face - the primitives and the operations are basically the same. So if you refactor your C++ -> Win32 implementation into C++ -> stable nontemplated API -> Win32 and then observe that the stable nontemplated API is essentially the same as pthreads with several minor differences here and there... you get N2178.
