IMO this is too specialized to include. It's small enough that applications can
do it themselves, but also fairly confusing unless your RDD is already sorted
in some way. I think we should just leave it for applications to do it. If you
are doing a skewed join operator for example, you can do it within the
implementation of that but not show it to the user.
