Jay Kreps resolved KAFKA-1072.

    Resolution: Fixed

I think this is solved with the partition.assignment.strategy option in 0.8.2

> Currently, there is no parallelism used when consuming a set of topics selected by a white list topic filter, if those topics all have a partition count of 1.  Currently, all topics that match the filter get assigned to the same thread on the same consumer, even though there may be plenty of different topics (and therefore many partitions to be consumed from).
> There are often good reasons to use a partition count of only 1 (e.g. to preserve message ordering).  For arbitrary scalability, over a large number of topics, this would be a great benefit to be able to consume topics balanced over a set of available consumers.
