// binary.  In the spirit of delta debugging, a pass initially tries to apply
// large chunks of reduction opportunities, iterating through available
// opportunities at a given granularity.  When an iteration over available
// opportunities completes, the granularity is reduced and iteration starts
// again, until the minimum granularity is reached.
