title: rails test database not clearing after some runs
body: <p>I am using rspec to test and I notice that after running the tests, it sometimes leaves some records in the test database. I'm not sure why. I have use_transactional_fixtures set to true in my config file. But they don't go away until I manually delete the records. Does anyone have a way to stop this?</p>
  
  <p>EDIT; before i said it was only when tests fail. that's no longer true.</p>
