Subject: drb question

I am trying the distributed Ruby examples from PickAxe using
ruby 1.7.3 (2002-11-17) [i386-mswin32] and drb-2.0b1

The simple example works as expected.

But how do I stop the server gracefully?

Code as follows

# Server Code: drb_srvr.rb
require 'drb'

class TstSrvr
    def time_now
        "It is:  " + Time.now().to_s
    end

    def bye(msg="")
        puts msg
        exit(1)
    end
end

srvObj = TstSrvr.new
DRb.start_service("druby://EMACHINE:5555",srvObj)
DRb.thread.join

#--------------------------------------------
#Client Code: drb_client.rb
require 'drb'
STDOUT.sync = true

cliObj = DRbObject.new(nil,"druby://EMACHINE:5555")

5.times { |i| puts cliObj.time_now; sleep(2); }

cliObj.bye

#-------------------------------------------
C:\> ruby drb_srvr.rb

In a different command window:

C:\> ruby drb_client.rb
