Yes, you should use KM's method, the reasons he gives in his comment to the File Locking Tutorial are all valid.

flock-ing a separate file lets you lock several files at once, including files that cannot be locked as you don't have a file handle on them and is generally a cleaner design than locking the file you are using.
