Falling asleep is hard because my brain is always racing, my quality of the sleep is trash and waking up every day feels like an act of torture. It's gotten so bad that at some point in the last couple of years, I started using three alarms to make sure I get out of bed in time for work: a dedicated sunrise alarm clock, my smartwatch and my phone as the final, 11th hour save in case the other two methods don't do the trick. As you might imagine, my partner, who is forced to also endure this horrid morning ritual, hates it.
执行到 sleep 时，线程会进入阻塞状态，操作系统把它挂起，不分配 CPU 时间片。但这个线程仍然被占用着，线程池里它的“坑位”一直没释放。如果同时有 200 个请求进来，线程池的 200 个线程全被占满，都在等 IO，第 201 个请求就得排队，哪怕 CPU 空闲 99%。，这一点在新收录的资料中也有详细论述
