And in most cases people will forget to set up TEMP_CONFIG when setting up a new environment. If it is possible to reduce the I/O traffic when running check-world by default and if we are able to make it faster with a parallel schedule, my take is to do by default instead of expecting the user to set up that all the time. That's less to think about. So I am +1 and +1 for Andres' suggestions on this thread. -- Michael
