   Thanks @ableegoldman !
   
   Regarding the client-capacity-vs-thread-capacity dilemma, I think I'm remembering that conversation a little differently. I thought:
   * in the "under capacity" case (where all clients have more threads than tasks), we would assign an equal number of tasks to all clients.
   * in the "over+under capacity" case (where some clients have more threads than others and a uniform assignment would saturate the smallest node, but there are still more total _threads_ in the cluster than tasks), then we'll assign tasks such that no node is over capacity.
   * in the "over capacity" case (where there are more tasks than threads), then we first fill up everyone's capacity, and then go back to a simple round-robin over _clients_.
