-------------------------------------------
> ... (Should + one.releaseBuffer(byteArrayManager); be inside a finally
> block?) ...
You make a good point that the array may not be released when the pipeline
eventually fails. We cannot call releaseBuffer(..) in a finally block since,
for the usual error cases, client will reconstruct the pipeline and retry
sending the same packets. I will think about how to fix it.
> Clients may get stuck waiting when using ByteArrayManager
