ChangeLog: 2/3/2006: Gengbin Zheng implemented packetization, and fix a bug related to buffer reuse/change in pending send 2/7/2006: Gengbin Zheng implement active message mode using callback short message pingpong time improved by 0.5us 2/8/2006: Gengbin Zheng implement buffering of future messages (I haven't seen out-of-order messages so far, but it may happen) Using POOL relies on charmrun set MX_MONOTHREAD=1.
