Comment (by teor):
nickm discovered that this issue is happening because consensus timings
are different in 0.3.3 and 0.3.4:
* In 0.3.3, there is at least one second_elapsed_callback() between
authorities asking for missing votes, and creating the consensus
* In 0.3.4, second_elapsed_callback() is removed, and there can be less
than a millisecond between authorities asking for votes, and creating the
consensus
We should ensure that there are always 2 seconds between asking for
missing votes, and creating the consensus. This timing is required by
0.3.3 and earlier, because:
* the remote authority responds in the first second, then
* the local authority retrieves the vote and creates the consensus in the
second second.
