I started looking at how I would implement table_exists() with a direct call that uses sqlite-utils to see if a table exists.

https://github.com/simonw/datasette/blob/82fec6048148b58748040a7e2caa163387e982a3/datasette/app.py#L303-L304

sqlite-utils needs access to the database connection - but the database connection itself is currently only available in code that runs in a thread inside the .execute() method:

So I'm going to need to refactor this a bit. I think I need a way to say "here is a function which needs access to the connection object for database named X - run that function in a thread, give it access to that connection and then give me back the result".
