Comment (by viboes):

 One of the factors making the difference is that the win32 doesn't mask
 the interruption.

 Once the attached patch is applied the measures are closer even if the
 win32 is yet better.


 Please could you try the attached patch on trunk?
 BTW, give the measure for the best sample as done on the performance test
 example/perf_shared_mutex.cpp
