Picks up #1764 again, which is @NinoFloris's idea to separate read and write operations to separate pools to prevent head-of-line perf issues.
Unfortunately the volatility of the updates benchmark makes it impossible to say with clarity how this does; but it does seem to improve perf in a consistent way. I suggest merging this and tracking what it does to updates for a few days, we can decide whether to keep it or not after that.
