Filehandles that are already opened (especially for writing) have may have already been modified, before the lock was applied. Consider: 
open(FOO, ">/tmp/foo") || die;   # You've altered the file!
flock(FOO, LOCK_EX) || warn;     # And now you bother to lock it?

Yeah, it's silly. But you'd be amazed at how often it happens.
