That would definitely do it, for now. But in reality, you need to update 
IPREM with whatever else you might add as well. And also, if there are 
any active telnet sessions going on, telnetd will not exit anyway.
I guess that would be another thing to implement. If telnetd is aborted, 
all users coming through there should be logged out and disconnected...
