Unfortunately,
kill(pid, 0)treats zombie processes as running. So it is impossible to implement periodical watchdog for a child processes.I propose new method
tryWait()in Poco::Process and Poco::ProcessHandle. It checks process status and returns immediately with value indicating running process or it's exit code.Also I have added distinction between exited and killed process return codes in
waitandtryWait.
