Before reporting an issue, please ensure you are using the latest release of fsnotify.

Which operating system (GOOS) and version are you using?

Linux: CentOS7 x86_64

Please describe the issue that occurred.

A race happened when Fsnotify created pipe and epollfd, which didn't live with golang exec. It would lead to unintended fd inheritance. Please checkout https://github.com/golang/go/blob/c659be4dc862cdf14a24134f2cfc16fa81e6d84c/src/os/file_unix.go#L190

Are you able to reproduce the issue? Please provide steps to reproduce and a code sample if possible.

Simply insert codes like below after creating a fsnotify watcher

cmd := exec.Command("sleep", "1000")
cmd.Start()

and checkout /proc/${sleep_pid}/fd, there would be file descriptions inherited from the parent
