Actually, I was (too subtly, as usual) referring to the fact that every
operating system has a different AIO interface, if they support it at
all, not suggesting that a wrapper library was an acceptable solution.
Most operating systems' AIO implementations are an afterthought and not
worth the trouble of using.

Instead, we should just bite the bullet and do multiple reads the
old-fashioned way when we hit a situation where the I/O window would be
unreasonably large and start hoping people have SSDs.
