I'm not sure.  I think it's worth keeping the test you have, and perhaps giving 
it a more descriptive name of what properties it's testing.  As far as how to 
test the rollback, nothing bullet proof is coming to mind.  Maybe you could get 
creative and introduce some faults / shutdown the HMS in another thread?
