Calling RemoteVariable.set does not seem to notify the listeners that the value has changed.  Naively adding a call to RemoteVariable.get into epicsV4.EpicsPVHandler after the set call does not help, as this only calls the BaseVariable listeners and not the function listeners.  (The distinction between RemoteVariable._queueUpdate which updates the BaseVariable listeners and RemoteVariable._doUpdate which updates the function listeners is lost on me.)
