[Question]: Exit Linter Daemon on Buffer Close

I'm using `eslint_d` with the configuration below. The issue I'm running into is that once a daemon is started for a particular file/buffer, it is not closed when the buffer is closed. This results in a large number of `node` processes running continuously on my machine (which I have to `pkill` on a regular basis).

Is there a good way to trigger the linter to exit when a buffer closes? I'm guessing this is not an issue for other linters as they don't (to my knowledge) run as daemons.

Thanks for any help in advance!

No repository files, tests, or entry points are mentioned. Start by tracing how eslint_d is started for a buffer and how buffer-close events are handled; done means establishing whether the daemon can be stopped on close and documenting or implementing the supported lifecycle behavior.
