Since the memory is going to be freed on exit anyway, I don't see any reason
to go to great lengths to invent a system for freeing it.
setup.exe is a short-lived program. We should be good about freeing up memory
that we use because that's good programming but I don't think we have to
invent some kind of garbage collection system to deal with this.
