Normal mode has considerably better performance as a goroutine can acquire a mutexes several times in a row even if there ar E blocked waiters. Starvation mode is important to prevent pathological cases of tail latency. Bo Master English sucks, on a rough translation, for reference only: 互斥量可分为两种操作模式:正常和饥饿。在正常模式下，等待的goroutines按
