Using `__del__` often closes the database on a different thread, which
is not supported by the sqlite module and produces a different warning.
Explicitly close the status database everywhere it is used.
I don't want to ever have to sort imports again. It's a poor use of
developer time. Automate this with a pre-commit hook, and check this on
CI.
Developers: I suggest you configure your editor to use
`reorder_python_imports`. It uses the standard sorting, and detects
first/third party libs well.
