   @eolivelli, Regarding the release/retain story, Here is the understanding:
   
   Before this change, read() return result as Iterable, and if user 
call Iterable.iterator() multiple times, the references of ByteBuf have 
potential to be broken, and hard to manage. 
   e.g. one of the iterator accessed some entry and then released the 
reference; while another iterator may still want to access the same entry. 
   
   By this change, each call of iterator() will inc the references, and after 
usage, caller will dec the reference, it is manage-able and more safe.
