title: Is Netty Free of GC via ByteBuffers?
body: <p>When we create a ByteBuffer and then continually reuse it Java does no GC on it.</p>
  
  <p>Netty provides ByteBuffers for its input and output.  </p>
  
  <p>Does it continually reuse these, by keeping an internal positioning, so that the buffers never need garbage collection?</p>
  
  <p>Or must something special be done by the implementor to ensure no GC?</p>
