Comment:
We could also have 'bzr pack' invoke a similar rpc,
as a followon.  We should also manually test that 'bzr pack' still works 
with
this patch in place.  (I don't think it will have broken anything, but
still.)

+        if response[0] != 'ok':
+            raise errors.UnexpectedSmartServerResponse(response)
+

Is that correct, or should it be calling translate_error?

Otherwise it looks good.
