----------------------------------------------------------

h3. Status
* {{TP.receive()}} now de-serializes both single messages and message batches
* TCP uses a pre-allocated buffer for each connection ({{TcpConnection}}), which grows on demand, rather than creating a new one for each message. This reduced memory allocation (UPerf, 4 nodes, 2M msgs/node) by ca. 1.8GB
* TCP_NIO2 now also pre-allocates a buffer (in {{NioConnection}}) and grows it on demand

> Investigate whether buffers can be reused on the receive side. JGRP-1989 already provides this on the send side. Goal: reduction of memory allocation rate.
