BOOST源码笔记(2) - boost::thread之内部干将interrupt_wait

    BOOST的Thread库博大精深，有很多的多线程概念在里面，今天就对其中很多call都用到的interrupt_wait的实现进行解释。首先，在BOOST文档中，有1个不得不看的概念，如下：

Predefined Interruption Points

The following functions are interruption points, which will throw boost::thread_interrupted if interruption is enabled for the current thread, and interruption is requested for the current thread:

• boost::thread::join()
• boost::thread::timed_join()
• boost::condition_variable::wait()
• boost::condition_variable::timed_wait()
• boost::condition_variable_any::wait()
• boost::condition_variable_any::timed_wait()
• boost::thread::sleep()
• boost::this_thread::sleep()
• boost::this_thread::interruption_point()

    这个是说，有这么多的call可以用interrupt来打断，既有纯打断（属于无所事事，就想打断型）- interruption_point; 又有在休眠等待中被打断（从睡梦中惊醒）- 如其他。下面来看看官方的interrupt的描述
