Discussion with Rob resulted in this proposal:

* CDOs' Channels property remains mutable
* CDOs aren't allowed to emit ChannelLost or Finished until all approvers have
returned from AddDispatchOperation (they should queue up the signals for later
sending if necessary)
* As a result, Approvers 
* Non-Approvers that are somehow given a CDO's object path (i.e. mostly
Observers) are required to connect to ChannelLost, connect to Finished and
GetAll(), as per the usual connect-signals-before-state-recovery doctrine

I'll spec it up on Monday.
