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.
“过了三天年，人人不得闲。老头拾牛粪，老妈纺棉线。”这是江淮之间的民间打油诗。北方也有类似的俗语。对于乡野大泽的老百姓来说，迫切的生计摆在眼前，没有那么多闲暇余裕去消遣。但是，元宵节依然是要过的，家乡的习俗是“早过十五晚过年”。正月十五的早晨，家里做一桌丰盛的早餐，倒不一定要有汤圆，那是除夕早晨吃的，可能各地的习俗有差异。
