    Any program that asks for a password on the command line should have
    the common decency to overwrite/obfuscate it, along the lines of,
    
    	case 'p':
    		passwd = optarg;
    		optarg = "********";
    		break;
    
    So that it doesn't show up in any "ps" output.
    
    Of course, there is still a window of vulnerability before the code is
    executed, but any long-lived daemon has no excuse for not doing this.
