      Description

      We have hit both the asserts in the test.

      Exhaustive:

      statestore/test_statestore.py:574: in test_slow_subscriber     assert (secs_since_heartbeat < float(sleep_time + 1.0)) E   assert 8.8040000000000003 < 6.0 E    +  where 6.0 = float((5 + 1.0))
      Stacktrace
      statestore/test_statestore.py:574: in test_slow_subscriber
          assert (secs_since_heartbeat < float(sleep_time + 1.0))
      E   assert 8.8040000000000003 < 6.0
      E    +  where 6.0 = float((5 + 1.0))
      

      ASAN

      Error Message
      statestore/test_statestore.py:573: in t     assert (secs_since_heartbeat > float(sleep_time - 1.0)) E   assert 4.995 > 5.0 E    +  where 5.0 = float((6 - 1.0))
      Stacktrace
      statestore/test_statestore.py:573: in test_slow_subscriber
          assert (secs_since_heartbeat > float(sleep_time - 1.0))
      E   assert 4.995 > 5.0
      E    +  where 5.0 = float((6 - 1.0))
      

      I only noticed this happen twice (the above two instances) since the patch is committed. So, looks like a racy bug.
