| * Test for bug 2612366: Conform results in UnitOfWork extremely slow. |
| * <p><b>Test Description:</b> |
| * <ul> |
| * <li>Conform results test using a wrapper policy. |
| * <li>Insure that the number of times unwrap is called is linear to the |
| * number of objects read in. |
| * <li>The test input is small to allow this to be run as a short |
| * regression test. The relationship between input size and calls to unwrap is |
| * the key. |
