Well... there is always the old date,time and pid combination... that works fine as long as the script doesn't handle multiple messages in a loop. Of course, if it does handle messages in a loop it is easy to tell what the last name you used was and increment a counter if it is the same.

There is always file locking with something like flock...

And I believe you can also use sysopen to create files if they aren't there and error if they are, but not 100% sure on that... something with O_CREAT and O_EXCL maybe...
