 When starting my dirauth, I see this line:

 [warn] Loaded 56168 entries from keypin journal. Found 5 corrupt lines, 0
 duplicates, and 15814 conflicts.

 I assume the corrupted lines happen because the file is not atomically
 written, so if the disk runs full (which occasionally happened in the past
 due to bwauth issues) we're corrupting the log.
