The tuple will be acked. Note that ackTuple is initialized to true and is
only set to false if we are in a situation where we are doing a bulk write, in
which case the tuple will be acked in the bulk writer upon the writing of a
batch of entries. So, when this loop is ended, it will ack on line 164.
