Mmm, I think that may happen e.g. if the creation doesn't exit but gets
a signal, because in the loop we only test WIFEXITED().  If think maybe
we should rather

    if os.WIFEXITED():
        if os.WEXITSTATUS(rv) != 0:     
            sys.exit(os.WEXITSTATUS(rv))
    elif os.WIFSIGNALED(status):
        print ("got signal %d" % os.WTERMSIG(rv))
        sys.exit(1)
    elif os.WIFSTOPPED(status):
        print ("got stopped with signal %d" % os.WSTOPSIG(rv))
        sys.exit(1)
    elif os.WIFCONTINUED(status):
        print ("continued")
        sys.exit(1)

To make sure that we properly exit() and return appropriate error
message.

Samuel
