Windows: getppid() is not supported.

The PID and thus parent process PID concept is not available in Windows
and MinGW at least lacks the API mechanism.

This may re-open an issue with kid processes notifying the coordinator
when they are shutting down. If so we need to find an alternative
mechanism to replace this use of kill(getppid(), SIGUSR1)
