int _tmain(int argc, _TCHAR* argv[])
{
	boost::thread *thread1 = new boost::thread( boost::bind(&Thread1));
	boost::thread *thread2 = new boost::thread( boost::bind(&Thread2));
	boost::thread *thread3 = new boost::thread( boost::bind(&Thread3));
	thread1->join();
	thread2->join();
	thread3->join();
	return 0;
}

明显停顿时间更长的Thread3在最后出现最多。
