Guard against invalid PIDs in process operations (#4401)

Guard against invalid PIDs in process ops

On Unix, kill(0, sig) sends the signal to every process in the
calling process's group. KillProcess(0) would SIGTERM thv itself
and any child processes sharing its group. FindProcess(0) falsely
reports "alive" via kill(0, 0). Both can be reached when a status
file contains PID 0 due to crashes or races during proxy startup.

Fixes #4400
