ClientFactory.clientConnectionFailed re-entrancy problem

from twisted.internet import protocol, reactor

class Stopper(protocol.ClientFactory):
    def clientConnectionFailed(self, connector, reason):
        print 'here'

def main():
    reactor.connectTCP("localhost", 12345, Stopper())

if __name__ == '__main__':

With Twisted 2.5.0, this results in here being printed once and the process exiting. With Twisted 8.0.1, this is the result:
