我使用 unix 已经有一段时间了，在过去的几年里，我觉得交换是一个时代错误，但我很好奇其他人的想法。
我的论点大致是这样的（假设没有全局 ulimit 或 OOM 设置的摆弄）：
There is little value in swap because if you need to swap out to disk,
odds are it's going to be a vicious cycle where an app will continue
to eat not only real memory, but swap as well until it gets OOM
reaped (_if_ it gets OOM reaped).
If you have swap enabled, it will only prolong this death march to
the detriment of other processes - and in the worst …swap ×1
