telnetd eating up the cpu

[tom reingold]

When someone telnets into our Pyramid and sends a lot of data to
stdout, the cpu usage goes up to 100% for the telnetd running on his
line.  This does not happen if he logs in using rlogin.  Nor does it
happen using rlogin or telnet into a Sun, so this definitely looks like
a Pyramid bug.

My test is as simple as:

	while true
	do
		cat /etc/passwd
	done

This will peg the CPU meter and slow performance for ALL users.

Any ideas or news on this?
