If you want to see this bug in action, try using the -s option, which will give you enough time to swap from one terminal to another and investigate.
如果您想实际体会一下这个bug,试着使用- s选项,这样程序运行时您就有足够的时间在不同的终端间切换并且进行观察。
Also, option 4 will be more limited, because every bug fix has to use the 2.0 approach.
此外,选项4也会受到更多限制,因为所有的bug修正都必须使用2.0的方法。
If you do not have access to a 2.0 processor that supports backwards compatibility, then you must choose option 1, 5, or a subset of option 4, where every bug fix must be a 2.0 solution.
如果没有支持向后兼容的2.0处理程序,就必须采用选项1、5或者选项4的一个子集,所有的bug修正必须采用2.0方式。
