 Sweet, it works!
 [https://gitweb.torproject.org/stem.git/commitdiff/fcf49ad Fix pushed].

 I tested this with the following. Prior to the fix tor would hang after ~3
 seconds, but with the fix things happily chug along.

 {{{
 import time

 import stem.process

 from stem.control import EventType, Controller

 tor_process = stem.process.launch_tor_with_config(
   config = {
     'ControlPort': '9051',
     'Log': 'DEBUG stdout',
   },
   take_ownership = True,
 )

 with Controller.from_port() as controller:
   controller.authenticate()

   def heartbeat(event):
     print "%s - %s / %s" % (time.time(), event.read, event.written)

   controller.add_event_listener(heartbeat, EventType.BW)

   print "Press any key to quit..."
   raw_input()
 }}}

 Thanks for the catch!
