      The main test thread is waiting to acquire the write lock of storesMutex, and a transport thread is waiting for a publisher to give it the keys of stale segments. There's no thread with a storesMutex read lock acquisition in the stack (although one thread is trying to acquire the read lock), so either we leak a read lock or we hold the read lock for longer than necessary:
