It will be used as fallback value in the acquire method, if no timeout value (``None``) is given. If you want to disable the timeout, set it to a negative value. A timeout of 0 means that there is exactly one attempt to acquire the file lock. :param mode: file permissions for the lockfile :param thread_local: Whether this object's internal context should be thread local or not. If this is set to ``False`` then the lock will be reentrant across threads. :param blocking: whether the lock should be blocking or not :param is_singleton: If this is set to ``True`` then only one instance of this class will be created per lock file.
