You may need to explain this expectation in greater detail. How do you
reconcile remote-IO-without-wait-time with having to access remote data, as
would be the case during preview generation? At face value there's always an
unknown amount of wait time, because we don't know network throughput and
latency, and then remote drive throughput and latency. Or put simply: the only
way not to wait is to not read data; when reading data we need to wait for the
IO.

Such as?
