start this before you fire up your socket stuff

reaper =
Thread.new do
   loop do
     Kernel.exit if gets == 'exit'
   end
end

if you type exit, your program will exit.  check out highline or  
search the archives if you want something more elegant - exiting a  
loop and accepting cross platform user input is a real can of worms  
made complex by the lack of getch() on *nix platforms, the  
idiosyncracies of termninal attributes, and buffering issues with pty  
vs not.
