We've kicked this around for a while, and I think we need to get it in

jruby -J-Xmx1024M -J-server run_my_script.rb
The -J option passes whatever's after it as an argument to the
underlying JVM. I've attached a patch (about to be committed) that does
it for the shell script, but I don't know how to do it in cmd scripts
(Windows).
