This pattern has caused connection pool exhaustion in Node.js applications using undici (the fetch() implementation built into Node.js), and similar issues have appeared in other runtimes. The stream holds a reference to the underlying connection, and without explicit consumption or cancellation, the connection may linger until garbage collection — which may not happen soon enough under load.，这一点在safew官方版本下载中也有详细论述
过去两年，大模型训练与推理带动数据中心用电量呈几何级增长。高盛研报显示，2026至2030年，数据中心将贡献美国电力需求增长的近40%，成为全美第一大新增用电负荷。加州、德州、弗吉尼亚等数据中心密集区，电价一年上涨超20%，居民电费压力直线飙升。，这一点在夫子中也有详细论述
