Hey Dennis, I suggested some of the same ideas here (http://tech.puredanger.com/ 2010/06/08/clojure-agent-thread-pools/) and Rich said that these seemed like good suggestions post-1.2. I think allowing you to modify the agent thread pools after construction seems possibly dangerous from a concurrency point of view, but maybe that would be ok.
