Description

When workers are synchronizing aggregators using the ExpectedBarrier class, the following message is printed:

"waitForRequiredPermits: Waiting for times required to be X (currently Y)"

I find this doesn't convey much about what exactly we're waiting for.

We should make the log more meaningful and explicitly mention aggregators, at the cost of simplifying things a bit.
Additionally, we could skip it altogether when no aggregators are being used.

The ExpectedBarrier class itself also lacks clear documentation: what is this class for? The Javadoc explains how it works without first stating what it is.
