"The more kernel threads block : the higher latency you introduce?" That's totally non-sensical; how : about you make EVERYTHING non-blocking then and let's just ditch : blocking for resources altogether because it "increases latency?!" : You're NOT increasing latency when you're blocking when you have : nothing available. I made my point badly, and given your understanding of it, I can understand why you think I'm nuts. I was speaking with language that wasn't tight enough. Thread that can block will have a larger variance in latency than thread that don't block. Even though I made that point badly, the variance is likely a parameter that isn't of high enough importance to have it imfluance the API/ABI. I'm sorry if you find arguing with me frustrating. To be honest, I'm starting to agree with your point of view on this in many instances.
