  * priority:  normal => minor


Comment:

 Yes, this would be useful to have.  It's more complicated to implement
 than it should be, though.  metrics-db is run in an hourly cronjob.  And
 it sometimes takes a good fraction of that hour.  We'd have to decouple a
 few more things to run only the consensus (and vote) download twice an
 hour.

 As a quick fix I just set up a second instance of metrics-db that runs at
 :45 and downloads whatever consensuses and votes it gets.  If it finds a
 consensus that wasn't published at :00 of an hour, it sends me mail and
 I'll copy files over to the main metrics-db instance to get them included
 in the tarballs.  If it happens twice per year, that should be fine.  In
 the long-term we should have a real fix though.  Reducing priority to
 minor, now that we have at least a workaround.
