咨询pthread_cond除代码聚合外的其他负面特性

Hey, I feel you on this. I've gone through loads of pthread_cond-related questions and resources—everything from step-by-step usage guides, when to use it vs semaphores, to real-world application scenarios.

The thing that's bugged me too is that while plenty of people will say "you don't need to use pthread_cond" as a reason to avoid it, almost no one actually lays out the specific downsides or pitfalls of pthread_cond variables clearly. I've put in a lot of effort searching through threads and articles, and I haven't come across any discussions that explicitly break down these drawbacks either—even though I was looking hard for exactly that kind of info.
