Ignore latency-updates while removing tracks. remove_tracks() calls disconnect_all() which can trigger the backend to perform a latency-recompute in a different thread (process thread). That calls Session::update_latency() which iterates over all routes including the one(s) to be deleted. At the same time disconnect_all() may propagate Port::PostDisconnect() leading to a lock contention. (no crash just a lot of unnecessary work. remove_routes() calls update_latency_compensation() which triggers a recompute if needed)
