FileListener 报错了，看了这种实现在go1.3都不行额

环境: maxos
golang: 1.13

terminal1

$ go run main.go
2020/02/25 19:29:16 process with pid 91709 serving :8080.
2020/02/25 19:29:16 process with pid 91709 stoped, error: net.FileListener error: file file+net : getsockopt: socket operation on non-socket.

切换到 linux 环境也是 bad file descriptor
