The frame pump counted the live seqs from the last replayed event, which
is right only when the replay carried something. A client whose cursor
already sat at the record's head replays nothing, so the pump restarted
at zero: the client's next resume then named seq 0 and replayed the
whole record, and every event it printed in between carried a number
that named something else.
Base the count on the cursor when the gap is empty. The test resumes at
the head of a finished turn and asserts the next live frame names the
record's next seq.
