I'm saying that swift throttle value will allow me to make full use of
all the nodes that Falkon makes available for me. I know that I had 26
jobs to be run, and I requested (and had) 30 nodes in the cluster.
Somehow only 24 jobs run in the first time, so I'm going to push up
the throttle value in Swift
