> The default Netty4 implementations of ByteBuf utilize manual reference counting to speed buffer recycling with minimal overhead.  Their initial evaluation also included exploration utilizing ReferenceQueue to utilize java gc for buffer recycling.  We should pick up their initial efforts and explore whether or not the performance loss is that great for our use case.  The particular commit is here: https://github.com/netty/netty/commit/6c16972a031b3e81b9bf17e381c43b9f0c010eba
