* Get storage advice for each cache in an FFT data server. Allows us to be more confident about the actual memory situation and cut over from memory to disc part way through an FFT calculation if necessary. StorageAdviser is now a bit too optimistic though (it's too keen to allocate large numbers of small blocks in memory).
