 If you do this:

  - create main_tub
  - create IntroducerClient
  - add IC as client of main_tub (setServiceParent(main_tub))
  - main_tub.startService()

 ...then you'll get "got introducer version" twice in the IC. If you move
 the "startService" up to before the setServiceParent, you only get one
 notification. Is there a race in Foolscap (foolscap.pb.Tub calls
 startConnecting on Reconnectors but sometimes does so twice). Could be due
 to "when does the reactor start" too (i.e. some of the startConnecting
 calls are in eventually()
