This module tries to find middle ground between one at a time and
all at once processing of data sets.
The purpose of this module is to avoid the overhead of implementing
an iterative api when this isn't necessary, without breaking forward
compatibility in case that becomes necessary later on.
The API optimizes for when a data set typically fits in memory and
is returned as an array, but the consumer cannot assume that the
data set is bounded.
The API is destructive in order to minimize the chance that resultsets
are leaked due to improper usage.
