/* This test exercises multiple rounds o fthe basic use of the MPS reader:
* - The 'producing' layer provides a buffer
* - The 'consuming' layer fetches it in a single go.
* - After processing, the consuming layer commit the data
* and returns back to the producing layer.
*
* Parameters:
* - with_acc: 0 if the reader should be initialized without accumulator.
* 1 if the reader should be initialized with accumulator.
*
* Whether the accumulator is present or not should not matter,
* since the consumer's request can be fulfilled from the data
* that the producer has provided.
