Trying to remember what I did here.. eager/max messages should work now, no RDMA yet. A number of other fixes and cleanups. I do know of two problems: Bad stuff happens when flooded with send frags too quickly - the BTL doesn't handle flow control. Certain IBM tests turn up a length assertion in the datatype engine - needs more investigation. This commit was SVN r10070.
