The tradeoff is complexity. The microcode must be carefully arranged so that the instructions in delay slots are either useful setup for both paths, or at least harmless if the redirect fires. Not every case is as clean as RETF. When a PLA redirect interrupts an LCALL, the return address is already pushed onto the microcode call stack (yes, the 386 has a microcode call stack) -- the redirected code must account for this stale entry. When multiple protection tests overlap, or when a redirect fires during a delay slot of another jump, the control flow becomes hard to reason about. During the FPGA core implementation, protection delay slot interactions were consistently the most difficult bugs to track down.
一只极其丰满的“老虎”骄傲地穿过舞池，Maggie姐不屑地撇过头，“隆的。”像Maggie这样的上一代香港妈咪，对内地小姐的态度确有几分微妙：她们喊价低，又拼命，很快就把传统的夜总会小姐比下去，再看看她们的外形，哪一个不是浓妆艳抹、凹凸有致。连Maggie姐也惊叹于这些内地女孩的拼命和坚韧：香港夜总会黄金时期，一大批内地女孩来香港淘金，中国城、大富豪都有内地小姐的身影，狠命做几年就挣到了第一桶金，然后金盆洗手，在香港嫁人，或回老家做生意。“她们很有规划，知道自己要什么，所以叫老虎，很厉害啊！”
