changing this

fd, err := syscall.Open(flockName, syscall.O_CREAT|syscall.O_RDONLY|syscall.O_CLOEXEC, 0600)

to

fd, err := syscall.Open(flockName, syscall.O_RDWR, 0) in https://github.com/juju/mutex/blob/master/mutex_flock.go fixes the problem

missing WR option?

It seems to me that O_RDONLY and 0600 are in conflict. I wonder if the behaviour varies between systems and is unpredictable...

Does simply removing O_RDONLY also work?
