I strongly disagree that this is how file locking should work. It is how it does work on Windows, but it is not how it works on Unix. The result is that you have an additional piece of complexity on Unix that applications need to be aware of, but when you are dealing with shared resources, the Windows behaviour is (in my experience) far harder to administer.

Furthermore it can be very convenient. For instance as a debugging aid it can be very nice to type in: 

tail -f /var/log/apache/error.log

[download]
and watch the result of writes made by Apache to its error log in real time as you are interacting with the browser. (Writes which you get in there with well-placed warn statements...) This works just fine on Unix. But Windows makes it far too easily for an application to make this kind of interaction impossible. :-(
