commit 58721ac24c684236c52c062a255c38f2f019fda5
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Fri May 24 13:31:10 2013 -0400

    Tweak 4282 unit tests for style, safety, correctness.
    
    We do our filesystem wrangling relative to get_fname() results, so
    that if we fail or crash, we can always clean up.
