为了避免这种情况，敏捷项目“执行”并再利用预构建好的二进制码，并且只有再必要时重新构建整个系统(例如，每夜或每周)。
To avoid this situation, agile projects typically "stage" and re-use pre-built binaries, and only rebuild the whole system when necessary (for example, nightly or weekly).
这意味着验证码的设计者们不能仅靠增加文字扭曲程度来打击攻击验证系统的人。
This means designers of CAPTCHAs cannot simply increase the amount of distortion to foil attackers.

系统内核所使用的内存空间通过特权码（privileged code，2级或者更低）来标记，以防止用户模式的程序访问到内核空间而发生页面错误。
Kernel space is flagged in the page tables as exclusive to privileged code (ring 2 or lower), hence a page fault is triggered if user-mode programs try to touch it.
