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.
