Similar comments as before. Link to `run` so users know what soft durability actually is (you also use text "if you don't want to wait on disk" in another command -- try to be consistent everywhere). Explain what non-atomic updates are, etc. I think you're doing amazing work, but this commit generally lacks consistency. You often use different text/phrasing to explain exactly the same arguments/concepts in different commands. I think the commit would see a huge improvement if you paid more attention to consistency of tenses/style/phrasing/etc. For example, if you explained "returnVals" in one command, explain it in *exactly using exactly the same text* in every other command, barring obvious replacements (i.e. command name)

This type of consistency is extremely important in all aspects for a coherent user experience. It definitely requires a lot more time, but the game is very much worth the candle.
