The traces look good to me, although of course it is always hard to read traces,
it's just a fact of life.

You mentioned that this is a server-only patch at this point; have you started
to think about what we should do to the client to take advantage of this?

Also, thanks very much for clarifying the 10 Meg maximum from the DRDA spec.

Have you thought about what a "good" value might be for the server? It seems like
there might be reasons that a value higher than 32K, but lower than 10 Meg, turns
out to offer the best tradeoffs of performance, memory usage, etc. I imagine that
we would want to run some benchmarks to try to investigate the buffering behaviors
and where the interesting points are in the performance of the network code. What
sort of measurements would be revealing?
