[Twisted-Python] Multiple client connections

I want to write a client that connects to a Twisted Server using pb.   
I want my client to make several connections. For example:

from twisted.spread import pb
from twisted.internet import defer

from twisted.internet.tcp import Connector
from twisted.internet import reactor
PORT = 8992

class ModelCalculator:
     def __init__(self, host, port):
         self.host = host
         self.port = port

     def add(self, a, b):
         self.factory = pb.PBClientFactory()
         deferred = self.factory.getRootObject()
         deferred.addCallback(self.connected, a, b)
         return self.result

     def connected(self, perspective, a, b):
         deferred = perspective.callRemote('calculate', a, b)
         deferred.addCallback(self.success, perspective)

     def success(self, result, perspective):
         self.result = result

     def failure(self, reason):
         self.result = None

     def stopReactor(self):

if __name__ == '__main__':
     calculator = ModelCalculator("", PORT)
     print calculator.add(4,5)
     print calculator.add(14,5)
     print calculator.add(24,5)
     print calculator.add(34,5)

As you see, I want to add many numbers and print out the result.   
This doesn't work because the reactor is been stopped in the  
stopReactor() method that is invoked in either success() or failure 
().  How can I change it so I can call my remote add() method many  
times without waiting for the reactor to be stopped? Is there a way  
that I can use the PB stuff without the reactor?
