The thing is that discussions like these can clear up misapprehensions and
increase the competence of the people who ultimately contribute to the node
ecology. People shouldn't fear to ask questions lest they be sniped by a
douche with a penchant for semicolons; That node performance test thread?
Same thing. I did a similar thing in the macOS kernel panic thread but it
was atleast marginally funny (and I did feel like a douche for doing it).
