在这期的5件事系列中，我将通过同步方法、volatile变量和原子类介绍多线程编程的一些更隐晦的方面。
In this installment of the 5 things series, I introduce some of the subtler aspects of multithreaded programming with synchronized methods, volatile variables, and atomic classes.
通过状态变量来同步多线程是一种很流行的方法。
A popular method of synchronizing multiple threads is through the use of condition variables.
多线程分发很容易产生同步问题，它产生多个可能互相干扰的事件处理线程。
Multiple-threaded dispatching can easily raise synchronization issues. It generates multiple event processing threads, which might interfere with each other.

Event kernel object is a kind of kernel objects to synchronize threads.
如果必须用多线程处理同一对象，则应该执行适当的同步机制，如临界区。
If you must have multiple threads manipulate the same object, you should implement the appropriate synchronization mechanisms, such as critical sections.
介绍了CORBA中的四种异步激发方式：多线程方式、单向异步激发方式、延迟同步激发方式以及异步方法调用方式，并讨论了各种异步激发方式的优缺点。
