I don't think there is any 100% safe way of doing this for an arbitrary process, but in practice it's probably fairly easy to get most of the way there. Some suggestions...

Most systems I've used _seemed_ to avoid reusing a PID at least for a little while. If this is true and your find/kill sequence is short enough, this should get you 99.99% there.

If you have root priviledge and the process you are trying to kill is owned by a non-root user, you could setuid to the user and then perform the kill. Of course this won't help if the same user gets the reused PID quickly enough.
