应用程序中的每个线程都需要内存来保存它的栈(用于在调用函数时保存本地变量和维持状态的内存区)。
Every thread in an application requires memory to hold its stack (the area of memory used to hold local variables and maintain state when calling functions).
就像其他运行时内存区一样，本地方法栈占用的内存区也不必是固定大小的，他可以根据需要动态扩展或者收缩。
As with the other runtime memory areas, the memory they occupied by native method stacks need not be of a fixed size. It can expand and contract as needed by the running application.
如果我们使用一个简单的内存区，我们要么必须用realloc或其它等效方法来扩展它，要么拷贝内插有替换的整体。
If we are using a simple buffer, we either have to extend it with realloc or equivalent, or copy the whole thing interpolating the replacement.
一个更好的解决办法是对内存区的两段扫描：第一段只是计算新内存区的长度，随后我们分配内存和拷贝带有需要的替换的数据。
A better solution is a two-pass scan of the buffer: the first pass simply computes the length of the new buffer, after which we allocate the memory and copy the data with the required replacements.
一段时间之后，人们又想出了一种防止该问题的新思路：将所有可执行代码转移到一个称为“ASCII保护(asciiarmor)”区域的内存区。
After some time, a new idea was developed to counter that problem: move all executable code to an area of memory called the "ASCII armor" region.
要达到这个目的，你可以使用错误注射引擎（Fault Injection Engine）或者调试器（debugger），甚至可能仅仅只需要手动把一个值写到相关内存区就行。
You might do this with a fault injection engine or a debugger, or maybe just by poking a value into memory by hand.

The database server manages the allocation and de-allocation of memory in this portion.
虚拟内存段：虚拟区用于维护和控制进程所需的资源。
Virtual memory segment: This virtual portion is used for maintaining and controlling the resources needed by processes.
在清单5中，使用.rept(或%rep)指令为10个双字创建内存数据区。
In Listing 5, the.rept (or % rep) directive is used to create a memory data area for 10 double words.
因为根页使用十分频繁，所以它通常驻留在内存缓冲区中。
Because the root page is used so often, it always resides in the memory buffer.
