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.
