Review comment:
I looked at the test a bit closer and now see that the batch size is set
as 10 in the `createSenderInVm()` method, so it might be good to add a comment
explaining that 4 batches are expected because each dispatcher thread will send
2 batches, since it's not immediately obvious when looking at the test what the
batch size is, or why 30 entries with a batch size of 10 would result in 4
batches rather than 3.
