macOS Big Sur: Retry file open when error is EINTR

[hiro-tan]

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

macOS: Big Sur 11.0.1
Machine detail: MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports), CPU: 2.3 GHz Quad Core Intel Core i7

Please describe the issue that occurred.

I upgrade macOS then unix.Open sometimes return error interrupted system call.
So when process reached https://github.com/fsnotify/fsnotify/blob/master/kqueue.go#L218 and error is EINTR, I want to retry file open.
This like below:

// This is another issue, but unix.Open return 2^32 - 1 as file descriptor when some error is occurred in my environment.
for watchfd == 0 || watchfd == -1 || watchfd == 4294967295 {
	watchfd, err = unix.Open(name, openMode, 0700)
	if (watchfd == -1 || watchfd == 4294967295) && err != unix.EINTR {
		return "", err
	}
}

But I can't decide if this is an effect of upgrading macOS or a problem in my environment.
Give me your opinion, please.
