Comment (by teor):

 We should only write the latest bad consensus to a file.

 We should only write signatures from authorities we trust to the sigs
 file. Otherwise, an authority's disk could be filled by a malicious server
 pretending to be an authority.

 Alternately, we could limit the file size(s).
