Garbage collection (mentioned in the article) is also a great example of integrated vs modular, with the same tradeoffs: when you handle it manually, it is integrated with the code - and it's possible to optimize/customize its performance much better than an automatic garbage collector.

An automatic garbage collector is a separate module: the details are separated from your code; different garbage collectors (with different strategies/tradeoffs) can be used without affecting your code; and development is cheaper.
