Review comment:
       Could we adjust the above comment on "The error is indicated in two 
ways: by setting the same error code in all partitions, and by setting the 
top-level error code.  The form where we set the same error code in all 
partitions is needed in order to maintain backwards compatibility with older 
versions of the protocol in which there was no top-level error code." ?

Review comment:
       If we can't merge this in 3.0, we will need to change the tag to 3.1.
