to get more coverage for cacao, it would be nice to build cacao as an additional
vm, and make this available as an option, adding to -client and -server an
-cacao option. This needs a conditional in the launchers not to start a new
thread, but otherwise the changes seem to be limited. Not sure if Zero/Shark
could be built this way as well.
