I hereby claim:

To claim this, I am signing this object:

	//! A reproducer of the 'database is locked' error.
	//! https://www2.sqlite.org/cvstrac/wiki?p=DatabaseIsLocked
	//!
	//! The error happens like this:
	//! ```
	//! thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: Database(SqliteError { code: 5, message: "database is locked" })', src/bin/multiple.rs:35:22
	//! ```
	//! The code is "5", while the wiki page says it is 6.
	//!
	//! ```toml
