The user nukes his telnet session ungracefully and whatever is reading from stdin then gets fed info something like "not a tty" or some other message it does not consider valid input. It falls into a loop to process the input, can't make sense of it, so loops back for more user input, and gets the same message -- it repeats ad infinitum and is a bummer. - Barrett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
