为此,美国想了很多办法,其中包括改进战斧导弹的技术,使其能在飞行过程中被重新安排目标,这样至少能在目标跑出去不太远的情况下继续执行任务。然而,当时美军全球精确打击的主力就是战斧巡航导弹,这款武器虽然射程远且非常精准,却是一款亚音速导弹。从锁定目标到飞过去,需要的时间单位以小时计算。

System CallsBlocking on channels and mutexes is one thing — the goroutine parks, but the M and P stay free. System calls are a different beast, because they block the entire OS thread.
The other three failure modes follow the same pattern. Erlang mailboxes are unbounded and provide no automatic backpressure, so if a process receives messages faster than it can handle them, the mailbox grows until the node runs out of memory and crashes. Fred Hébert (author of Erlang in Anger) built an entire library called pobox specifically for this problem, noting that “high throughput Erlang applications often get bitten by the fact that Erlang mailboxes are unbounded.” Message interleaving from multiple senders is nondeterministic, creating ordering races that the language can’t prevent. And Erlang messages are dynamically typed, so a process can send any term to any other process with no compile-time check that the receiver expects it.
