> The fact that we have special-case code in the MapsideJoinStrategy for the
> in-memory and MR-based Pipeline instances has always bugged me, so I set out
> to eliminate the distinction between the two impls by creating a new
> interface, ReadableSourceBundle<T>, that encapsulates the MR and in-memory
> specific logic for doing mapside joins in order to remove the special-case
> code in MapsideJoinStrategy and hopefully make other implementations that use
> our mapside-join patterns much easier to test.
