Comment:

 It looks like this patch fixes some chutney failures. It replaces
 "mismatched digest" with "vote received too late".

 I'm going to see if I can get the unit tests compiling, and a spec patch.

 Nick, should we activate this new code:
 * on all directory authorities, or
 * just on directory authorities in test networks?

 arma has been running it on moria1 for some time now.
