Unit Tests

- Added unit tests for bug 819, on behalf of Matt Kraai.
- Created a new, single test for cleanup that replaces 6.  It's makes
  for shorter unit tests, and adds less test count inflation.  Over
  time, all tests should be modified in a similar way.  This will
  probably cut the total number of unit tests in half, but that's not
  the important metric.
