If you have the freedom to choose the logfilename then why
not use a new filename for *each* message? (that was my
suggestion). You might want to prepend a timestamp
if you can't reliably access 'mtime' on that machine.
Reading all the messages in and sorting them is easy.
This is way simpler than any locking scheme.
