Comment (by teor):

 Here's what I suggest:
 1. Run chutney on master
 2. Take copies of the torrc, state, and sr_disk_state files
 3. Run them through file -> object -> file
 4. Use the output files as inputs to unit tests
 5. Make the unit tests do file -> object -> file -> object
 6. Check that both files and both objects match
 7. If the files don't match, and the differences aren't meaningful,
 either:
   * mock the functions that return variable content, or
   * exclude the variable content from the test
