Description
I have a simple Express server running Level and if I stop and start express sever back up a few times while testing I get issues with Lock file. How do I prevent?

Research direction
Start with the reported errors in node_modules/abstract-level/abstract-level.js and review how the Express server and Level database are opened and stopped during repeated restarts. Reproduce the lock-file failure if possible; done means repeated stop-and-start cycles no longer produce “Database is not open” or “iterator not open” errors.
