Hi [~ndillman]

 We no longer see the issue as it was worked around with staggering responses for all of the "bulk response" messages (ie: view change, etc).

This may have reduced the chances of such a scenario happening, but I don't think it eliminated it completely. In my next comment, I'll show how such a scenario can be reproduced.

Yes, a solution will involve a non-coordinator becoming merge leader, but this requires code changes in 3 places: the merge detection, the merge leader determination and the actual merge merge.

> In the case below, a merge doesn't seem to happen. Write a unit test to reprodue this.
