The relationship + between ForwardsOnlyDataReader and CachingDataReader is an example of this). + Since the interface presented to the user is still forwards-only, queues are used to + store this information, so that dequeueing as we go we give the garbage collector the best opportunity + possible to reclaim any memory that is no longer in use. + ForwardsOnlyDataReader being used to actually + obtain the information from the server means that the "leg-work" is still only done (and need only be + maintained) in one place. + This class exists to allow for certain potential backwards-compatibility issues to be resolved + with little effort on the part of affected users.
