推荐答案

在OSX上使用select.kqueue()代替使用poll.它与Linux上的'epoll'类似，因为您可以更有效地注册可在异步代码中使用的文件描述符/文件系统事件的类型.比轮询更有效.

Instead of using poll, use select.kqueue() on OSX. It's similar to 'epoll' on Linux in that you can more efficiently register for types of file-descriptor / file system events which can be used in asynchronous code. Much more efficient than polling.

否则，等效项只是在一会儿内运行一个阻塞的select.select()True:循环发生某种超时?

Otherwise, the equivalent is just running a blocking select.select() inside a while True: loop with some sort of timeout?
