I don't *think* that Dmitriy was implying that there has to be a lock step.
This is what the protocol says about the basic.ack command:
"If set to 1, the delivery tag is treated as "up to and including", so
that the client can acknowledge multiple
messages with a single method. If set to zero, the delivery tag refers
to a single message. If the multiple
field is 1, and the delivery tag is zero, tells the server to
acknowledge all outstanding messages. "
