Under what conditions is exponential segment sizing preferable to fixed size segments? Are there any specific algorithms or situations where this is especially good? It seems like the likelihood of large amounts of wasted space is a major downside.
It's always better - the increase in indexing complexity is negligible, and it completely eliminates resizing of the top-level array. It also reduces the number of calls to `malloc` while keeping capacity proportional to active size.
