    Good catch. I was wondering whether it is better to count in a consistent way, too, e.g.
count the size of each buffer or each record on both A and B (now we have per record on the
output side and per buffer on the input side).

> In 1.2-SNAPSHOT running a large scale job you see that the counts for send/received records
are inconsistent, e.g. in a simple word count job we see more received records/bytes than
we see sent. This is a regression from 1.1 where everything works as expected.
