Real-mode programs freely execute CLI and STI to control interrupts, PUSHF and POPF to manipulate flags, INT n for DOS and BIOS calls, and IN/OUT for hardware I/O. In normal protected mode, these instructions are privilege-checked -- they execute normally if the caller has sufficient privilege, and fault otherwise. The 386 can't simply let V86 tasks execute them freely -- a DOS program disabling interrupts would bring down the whole system -- but trapping on every INT 21h call would make V86 impractically slow.
But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.

作为一部兼具学术底色的普及读物，《法律深处是人心》蕴含深厚的历史知识与法学理论。书中所引案例，囊括了中华法系具有代表性的制度、思想与文化，阐扬了民惟邦本、明德慎罚、德主刑辅、隆礼重法等区别于其他法系的独特文化标识。如在东汉“孙章矫诏案”中，中常侍孙章将兄弟共同犯罪、重判兄长的诏令错念成重判兄弟两人，导致弟弟被误杀，按律构成“矫诏”罪，当处腰斩。但律学家郭躬从“君子原心”的古训出发，强调审案需探究动机，主张孙章属于过失犯罪，建议依律判处罚金，最终汉明帝认可其建议，连连称“善”。这种审慎态度，彰显了中华法系“明德慎罚”的人本主义色彩。
