"Still synchronous operations" of items in the group? Come on, grouping
brings nothing if items are output synchronously to the caller. Coalescing
helps if and only if individual items in the group are output
asynchronously to the caller and to the receiver. In other words when the
interested parties re-synchronize only at the ends of a group. In which
state relatively to the output is the caller between the ends of a group?

No thanks. We are actually paid for designing such tests, so we have plenty
of.
