- * We try to use the minimum number of stages which is enough to keep the tape
- * constantly streaming. To accomplish that, we implement a feedback loop around
- * the maximum number of stages:
- *
- * We start from MIN maximum stages (we will not even use MIN stages if we don't
- * need them), increment it by RATE*(MAX-MIN) whenever we sense that the
- * pipeline is empty, until we reach the optimum value or until we reach MAX.
