   > Could you describe what caused the segfault and why this fixes it?
   
   Even though the `flush_counter` is an atomic, incrementing it and checking its value are 2 separate operations and running them in parallel could create an ordering where the checked value is never 1. This can occur quite often if this thread is run every 1ms. Because of this the repository is not stopped before it is destroyed.
