And Christophe's latest improvements to transient support for maps improves the running time of my k-nucleotide benchmark program from about 12 minutes to about 9.5 minutes. Very nice stuff. It isn't in Rich's clojure repository yet, but you can get the changes from Christophe's github repo if you want to try it out.
