AFAIR, I just said that I'd find it hard to trust any complex mechanism
that was being used *only* during WAL replay. If we want to invent a
pre-reader process, or aio, or whatever, we should try to get it to be
exercised during normal use as well. We're far more likely to find the
bugs in it that way.
