util.startup: Close state on exit to ensure GC finalizers are called Ensures a last round of garbage collection and that finalizers are called. Fixes things like proper closing of SQLite3 state. There are more calls to os.exit() but most of them exit with an error or in a case where a final GC sweep might not matter as much. It would be nice if this was the default. Calling util.statup.exit() everywhere may be sensible, but would be more involved, requiring imports everywhere.
