I hope you are aware that file locking doesn't prevent any process from doing anything - apart from setting a conflicting lock of course - if you didn't explicitly request mandatory locking.

The default is advisory locking, which expects processes to check for and honor locks voluntarily.

Mandatory locking is frowned upon on systems that have it (System V derivatives) and difficult (Linux) or impossible (BSD derivatives) to enable on others.
