boost thread interruption

#include <iostream>
#include <boost/thread.hpp>

void f() {
  while( 1 ) {
    std::cout << "interrupt OK" << std::endl;
    {
      boost::this_thread::disable_interruption di;
      std::cout << "interrupt NG" << std::endl;
      boost::this_thread::interruption_point();
      {
        boost::this_thread::restore_interruption ri(di);
        std::cout << "interrupt OK" << std::endl;
      }
      std::cout << "interrupt NG" << std::endl;
    }
    std::cout << "interrupt OK" << std::endl;
    boost::this_thread::interruption_point();
  }
}

int main() {
  boost::thread t(f);
  t.interrupt();
  t.join();
  return 0;
}

おおーっ、スゲー。windowsでも中断するよ！disable_interruption の意味がいまいち、よくわかんねーけど、規模が大きくなったら効いてくるのかな？
