problem with remove lock file in windows

[allaVolkov]

The following code works without errors in Unix and ends with error Remove of lock file failed with: remove C:\Users\i019379\go\src\testLocking\lock.lock: The process cannot access the file because it is being used by another process. in Windows.
Thus in Windows it's impossible to remove lock file if more then one process tried to make locking.

func main(){
	wd, _ := os.Getwd()
	lockfile :=  filepath.Join(wd, "lock.lock")
	lock1 := flock.New(lockfile)
	locked1, _ := lock1.TryLock()
	if !locked1{
		fmt.Println("Error - First tryLock failed")
		return
	}
	lock2 := flock.New(lockfile)
	locked2, _ := lock2.TryLock()
	if locked2{
		fmt.Println("Second tryLock succeeded")
		return
	}
	err := lock2.Unlock()
	if err!=nil {
		fmt.Println("Unlock of second lock failed")
		return
	}
	err = lock1.Unlock()
	if err!=nil {
		fmt.Println("Unlock of first lock failed")
		return
	}
	err = os.Remove(lockfile)
	if err!=nil {
		fmt.Println("Remove of lock file failed with: "+err.Error())
		return
	}
}

@allaVolkov is this still present on v0.7.3? I don't have a Windows system I can test on.

I'm seeing this error using Windows via GitHub Actions:

profile_test.go:790: want no error, have error saving config file: error writing to config file: write C:\Users\RUNNER~1\AppData\Local\Temp\fastly-temp-2402719425\config.toml: The process cannot access the file because another process has locked a portion of the file.

I'm using version 0.8.1

I tried to reproduce the problem (I use the code in the issue description) on GitHub Action (Windows), but I could not get the error with v0.7.2, v0.7.3, v0.8.0, v0.8.1, and v0.9.0, etc.

I tried:

Version	Status
v0.7.0	🔴
v0.7.1	🔴
v0.7.2	🟢
v0.7.3	🟢
v0.8.0	🟢
v0.8.1	🟢
v0.9.0	🟢

So I don't know what to do: the Windows FS is a parallel world where even Go needs a dedicated internal package to "eliminate spurious errors".
https://github.com/golang/go/blob/master/src/cmd/go/internal/robustio/robustio.go

I need something to reproduce the problem with the current version.
