It's probably related to bug 1479035. The lifetime handling for nsThread wrappers is pretty hairy right now, and there are still some pretty easy ways to leak them if a thread does the wrong thing. Although, at the moment, I think that probably requires a background thread creating a thread wrapper after xpcom thread shutdown, since we explicitly clear the list when the thread manager shuts down, so I may need to do something extra to prevent that possibility.
