> In the BufferPool, we have a {{NoSpamLogger}} that gets called in some conditions (like
when we're at or near the cap in a given pool), which has some string formatting on it. In
situations where that log line is invoked, that string formatting gets called before the rate
limiting, which becomes expensive.
