 Review comment:
   > Since, in case of using the real RateLimitPolicy in normal code, the 
instances of them will be created per every readLoop() thread (right?). So, we 
need to test it in the same way with mock policies.
   
   It's possible for a custom RateLimitPolicyFactory to return a singleton 
instance of RateLimitPolicy, and I think that should be fine (as long as it's 
thread-safe). So maybe we shouldn't assume that they will always be different 
instances.
