Run the wait loop of the postscript against real processes. A process that is
still running is reported as still there, and the loop gives up instead of
waiting for ever. A process that has ended is reported as gone, and no time is
spent on it. The loop runs with a shorter bound so that the test does not spend
the whole timeout, and the bound of the postscript is checked on its own.
Cover that the check for a running process sends no signal, that the daemon
still gets the signal it cannot catch, and that the wait comes before the new
daemon starts.
