> Currently, when performing a round-robin partitioning each task will sequentially partition
starting with partition "1". This is fine in the usual case where the number of partitioned
objects greatly exceeds the number of channels. However, in the case where the number of objects
is relatively few (each, perhaps, requiring a large computation or access to an external system)
it would be much better to begin partitioning at distinct indices (the task index).
