Review comment:
It's a little bit surprising that the `ClusterDistributionManager` test,
mocks the `ClusterDistributionManager` ;-) But I get it and it's ok. It's
really a test of the inner `DMListener` ✓

Review comment:
ah now that this inner class is static we have to use an accessor to get
at the test hooks ✓
