(Sway dev mentioned in the article here.) To be clear, this loop doesn't exist in Sway proper: it lives in json-c, a third-party library used by a lot more than just Sway. A lockup bug was reported to a lot of projects using json-c at the same time. This really wasn't a Sway/Wayland thing, we just happened to be the first to diagnose and contribute a fix upstream.
