CTRL_LOGOFF_EVENT or CTRL_SHUTDOWN_EVENT to the process, Notify will
return syscall.SIGTERM. Unlike Control-C and Control-Break, Notify does
not change process behavior when either CTRL_CLOSE_EVENT,
CTRL_LOGOFF_EVENT or CTRL_SHUTDOWN_EVENT is received - the process will
still get terminated unless it exits. But receiving syscall.SIGTERM will
give the process an opportunity to clean up before termination.
