Yes, about. It's really a judgement call; you're looking for the approximate
combined RAM available for disk caching and shared mem. However, this is
just used as a way of estimating the probability that the data you want is
cached in memory, so you're just trying to be order-of-magnitude accurate,
not to-the-MB accurate.
