Patch Hurdles

Author: Here is a patch to improve performance in this particular usecase, see the results from this micro-benchmark

Skeptic: What about outside of a micro-benchmark?

Skeptic: Might it negatively impact different workloads?

Skeptic: Changing around this code in HEAD will make it harder to maintain the back-branches

Skeptic: The patch adds complexity for only a possible small performance gain

Skeptic: Bizarre platforms may not properly implement the new system or library call you are relying on
