Review comment:
Thanks for the explanation.
The problem was that the output didn't match the expected one. The reason
was that requesting partitions now also requires a mailbox step.
After your comment I replaced the fix with:
```
for (int i = 0; i < testHarness.inputGates.length; i++) {
testHarness.processSingleStep();
}
```
Does it look good to you?
