I have to dive into that. A good excuse to start with Clojure again. ;-)

I do not insist on it, but that is what I know right now. I have to find
out how to do this also, because it did not work at the moment.

Did not work either, but at the moment I use:
export JVM_OPTS=-Xmx512m
For the moment that does the trick.
Need to free some time to dive in these things.
