I've been using that latter pattern for new tests (and plugin tests) for quite a while now, but I never took on the job of refactoring all of the old ones.
A search for `(app_client):` across the whole project currently returns 194 results which might be a reasonable target to try switching to the new pattern as a starting point.

I'm going to see if I can switch to that for the majority of Datasette's tests. Might find that doing so both fixes this ""too many open files"" issue AND gives me a significant speed improvement to the test site too!
Hopefully I can do most of the work on that in this big ugly function:

It doesn't happen in CI, and it turns out that's because CI runs `pytest -n auto` which splits the tests across multiple parallel processes.
I've been working around the error on my laptop using `pytest -n auto` there too, but I'd rather not have to do that.
