The situation definitely improves for me after closing the eww buffer,
but Emacs is still sluggish. I assumed these extra processes were to
blame, but perhaps that's not right. I don't know what else could be the
culprit though.

Well, those are open network connections (which url.el keeps around),
and aren't processes, and should consume approximately zero CPU...

I tried this, and Emacs went back to using 0% CPU after killing off the
ewww buffer, so I'm unable to reproduce this.

Eww is slow and makes Emacs slow when visiting a website with (for
example) gifs[1]. Which is understandable, given that a text editor is
trying to display a modern web page.

However, Emacs is slow even after killing the eww buffer. M-x
list-processes shows that several processes are still lying around. Is
there a way to make eww kill these?
