 And what I meant with the GCC comment, is that the only way I have gotten
 the situation to work correctly is if I used
 std::this_thread::sleep_for().

 Yes, even with boost::this_thread::no_interruption_point::sleep_for:

 Here is the sample code(modified from an above example)

 #include <iostream>

 #include <boost/thread.hpp>
 using namespace std;

 void testfunc() {

         int i = 0;
         while(true) {
           //Turn system clock back now and loop will no longer print
                 std::cout << "Testing: " << i << std::endl;
                 boost::this_thread::no_interruption_point::sleep_for(
 boost::chrono::milliseconds(800));
                 i++;
         }
 }

 int main() {

         boost::thread th = boost::thread(&testfunc);
         th.join();

         return 0;
 }
