Review Comment:
   Ignore this, was just playing around here. The bulk of this change will be 
in the tests. I think for transactions we need to parameterize to test 
transactions which commit to a single branch AND we need to have tests for 
committing operations on different branches in a single transaction (which is 
where things become more interesting).
