这个问题似乎很有趣，它使我有理由研究Guppy / Heapy，对此我表示感谢。

我尝试了大约2个小时，让Heapy监视函数调用/进程，而又没有 零 运气地修改其源代码。

我确实找到了一种使用内置Python库完成任务的方法resource。请注意，文档没有指出RU_MAXRSS值返回的内容。另一个SO用户注意到它在kB中。运行Mac
OSX 7.3并看着我的系统资源在下面的测试代码中攀升，我相信返回的值以 字节为单位 ，而不是千 字节 。

我如何使用resource库来监视库调用的10000英尺视图是在一个单独的（可监视的）线程中启动该函数，并在主线程中跟踪该进程的系统资源。下面是您需要运行以对其进行测试的两个文件。
