Again, I don't find any routine holding `fmut` and there's no warning log entry about a recovered panic. If a function in a goroutine exits without releasing a lock, that would keep the lock and wouldn't show up in the trace in any way, would it? If it doesn't, that seems like the only possible explanation left to me.
I just discovered something horrible (hint, a change of mine) - PR incoming. I am wondering how integration tests didn’t trigger this (I assume they have deadlock detection enabled).
