Well, OK, maybe not. I don't think the problem gets any worse than if the process id is limited to 15 bits, in which case exactly the same id could end up belonging to a different process.

Currently kill(1) can take a pid or a process name. It should let you redundantly specify both, and (without any race condition) check that they match before sending the signal.
