In Example 8.10 we suggested the possibility of sorting record fields by their alignment requirement, to minimize holes. In the example, we sorted smallest-alignment-first. What would happen if we sorted longestalignment-first? Do you see any advantages to this scheme? Any disadvantages? If the record as a whole must be an even multiple of the longest alignment, do the two approaches ever differ in total space required?
