[Twisted-Python] resolution failure after upgrade to twisted 2.0

[Paul Pelzl]

Hello,

I maintain a wxPython application that uses Twisted for the networking
back-end.  After upgrading from Twisted 1.3 to 2.0, the application
fails to connect to a given hostname (e.g. "localhost"), although
everything works fine if an explicit IP address is provided.  My
application runs the Twisted loop by polling with a timer, like so:

------------------------------------------------------------------------
class MyApp(wxApp):

   def OnInit(self):
      ...
      EVT_TIMER(self, TIMERID, self.OnTimer)
      self.timer = wxTimer(self, TIMERID)
      self.timer.Start(250, False)
      ...


   def OnTimer(self, event):
      reactor.runUntilCurrent()
      reactor.doIteration(0)


   def connect(self, event=None):
      ...
      reactor.connectTCP(hostname, portNum, MyClientFactory())


reactor.startRunning()
app = MyApp(0)
app.MainLoop()
------------------------------------------------------------------------

Any idea what's going on here?  I suspect this guy is dealing with a
related issue:
