  21 # DESCRIPTION:
  22 #       Ensure that we can checkpoint a pool that we just rewound.
  23 #
  24 # STRATEGY:
  25 #       1. Create pool
  26 #       2. Populate it
  27 #       3. Take checkpoint
  28 #       4. Modify data (include at least one destructive change)
  29 #       5. Rewind to checkpoint
  30 #       6. Verify that the data before the checkpoint are present
  31 #          and the data after the checkpoint is gone
  32 #       7. Take another checkpoint
  33 #       8. Change state again
  34 #       9. Verify the state at that time
