I agree with others that you want to do something other than kill the
telnet session, like unplugging the cable. I've seen similar behavior out
of cyrus that I thought could easily be people on laptops shutting their
computers down hard, in some way that the TCP/IP stack never got a chance
to clean up the connection properly. With a QUIT or a kill, you're giving
the OS a chance to do the right thing.
