Using `Deno.FsFile.prototype.readable` with `Response`

I was trying to stream a file into a response with the snippet:

const file = await Deno.open(path);
const resp = new Response(file.readable);
file.close();
return resp;

const file = await Deno.open(path);
const resp = new Response(file.readable);
file.close();
return resp;

but it throws a BadResource error. This makes sense, because closing the file would destroy the associated stream, but if I have to close the file at some point, how can I put it in a Response? afaict any way I do it will either error or leave a leak. I guess I could add a finalizer for the file but that seems silly.

DuckDB deno package broken & npm package segfaulting

Has anyone had any luck using DuckDB with Deno? I've tried with the npm package with segfaults on a basic test query, and with the denoland package with fails on initialization (which is especially unfortunate because it was made by one of the deno maintainers? oh well).
