> The SlingHttpServletResponseImpl contains the request counter, which is a 
> static value incremented on each request. In case of heave concurrency, this 
> counter may yield the same value for two different requests.
> Using an AtomicLong (instead of int) we can ensure atomicity of update and 
> retrieval and at the same time increase the number of unique request ids (int 
> was probably wrong anyway in this respect and it should have been long from 
> the start).
