Commit2b7aa32(topology_coordinator: Refresh load stats after table is created or altered) registered topology_coordinator as a schema change listener and added on_create_column_family which fire-and-forgets _tablet_load_stats_refresh.trigger(). The triggered task runs on the gossip scheduling group via with_scheduling_group and accesses the topology_coordinator via 'this'. stop() unregisters the listener but does not wait for any in-flight refresh task. If a notification fires between _tablet_load_stats_refresh.join() in run() and unregister_listener in stop(), the scheduled task can outlive the topology_coordinator and access freed memory after run_topology_coordinator's coroutine frame is destroyed. Wait for the refresh to complete in stop() after unregistering the listener, ensuring no task can fire after destruction.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
